I've put Debian-testing (from about september 2005) on my Maxdata Eco 4000A notebook, with kernel, 126.96.36.199 (before I used 2.6.14-rc5 and 188.8.131.52, they work too). All important things works OK.
Main things that don't work for me are: S-video out and the SD cardreader.
From 2.6.17 or thereabout I start to experience infrequent lockups, usually about 5 min after boot.
Below I describe in more detail my experiences with my Maxdata Eco 4000A Laptop & Linux (Debian)
Oh, using wget, the max speed I get is about 2.51MByte/s (20.1Mbit/s), rather slow for a 54Mbit connection, but maybe my el-cheapo SWEEX access point is guilty for that. This is with the signal-strength indicator at 97%. The transmission speed rarely drops below 1.5MByte/s, so it feels relatively stable.

When ec_burst=1 isn't handled,
in /proc/acpi/battery/BAT0/state the remaining capacity is usually shown correctly, but not always. cat-ing from the file often breaks halfway with an error.
Thus, gnome battery charge monitor 2.8.2 cannot read it consistantly, and
often complains about "no battery present", or "battery low", even though
there is a fully charged battery present.
Furthermore, in /proc/acpi/battery/BAT0/state the 'present rate' always seems 0:
# cat /proc/acpi/battery/BAT0/state present: yes capacity state: critical charging state: charged present rate: 0 mA remaining capacity: 1289 mAh present voltage: 11492 mVAlso, when the ec_burst=1 isn't given, the kernel spits out the following:
Oct 14 23:01:20 localhost kernel: ACPI-0412: *** Error: Handler for [EmbeddedControl] returned AE_TIME Oct 14 23:01:20 localhost kernel: ACPI-0508: *** Error: Method execution failed [\_SB_.PCI0.BAT0._BST] (Node cbf84fe0), AE_TIMEFirst discharge lasted 2:08; charging again took about 4h (while the laptop is switched on).

CPU Idle Power States: /proc/acpi/processor/CPU0/info reports power management: yes, and /proc/acpi/processor/CPU0/power reports max_cstate: C8. Unfortunately, whatever I do, the active state always is C2, so it looks like it doesn't really do anything useful.

CPU throttling Doesn't work.
It works (at least using this script, but versions before 2.6.14-rc3 need a (small) patch from Rafael J. Wysocki <firstname.lastname@example.org>. Without the patch (at least in 184.108.40.206 through 2.6.14-rc2), the system freezes when there isn't enough swapspace to write the memory to.
I'm now using the "firmware" method to write the data to disk,
echo firmware > /sys/power/disk echo disk > /sys/power/state
Time to powerdown: 14 sec
Time from powerup to working X: 37 sec (of which 12 s is spent in BIOS).
After powerup, the only thing that doesn't come up automatically is the Ralink WiFi card, so I have a little script that does "ifdown/suspend/sleep 4/ifup ra0" automatically.
For the freeze-output (without the patch), see here
wget http://puzzle.dl.sourceforge.net/sourceforge/cdctl/cdctl-0.15.tar.gz tar -xvzf cdctl-0.15.tar.gz cd cdctl-0.15 ./configure make ./cdctl --lockdoor=1 Now the CD/DVD drive door will not open, even if it's empty and you push the eject button on the drive door. ./cdctl --lockdoor=0 Now you can open it again normally.

I haven't tested everything yet; I'll try to add more info later. If you would like me to test something, please email me.
