various problems with Acer TM654, suspend, ACAD, radeon

Hello dear ACPI fellows!

I am using an Acer TravelMate 654LCi with debian/sid on it running
always the latest -mm kernels (ATM 2.6.8.1-mm3).

I have encountered the following problems with ACPI:

- The battery does not deliver the discharging rate, it is always 0:
	present:                 yes
	capacity state:          ok
	charging state:          discharging
	present rate:            0 mA
	remaining capacity:      2749 mAh
	present voltage:         11520 mV

- The AC adapter does not send *any* events.
	Neither when plugged in nor unplugged.

- The battery gives periodic events:
	battery BAT1 00000080 00000001
	battery BAT2 00000080 00000000
  (although there is NO battery 2 installed!)

No for something related to this: Suspend2XXX.

With S2D I had success up to 2.6.7-mm5 (I didn't check all the inbetween
kernels), but with 2.6.8.1-mmX and rc4-mmX the laptop suspends without
any problems (besides I have to stop mysqld), even with X running (ATI
Radeon 7500M 0000:01:00.0 VGA compatible controller: ATI Technologies
Inc Radeon Mobility M7 LW [Radeon Mobility 7500]).

With the newer kernels resuming does not work anymore, there are many
Ooops. (I know, I should write them down on a sheet of paper, I will try
to collect them with usb-serial console).


For S2R: I got this pretty nice working, I had to stop USB, and various
other stuff, and with boot-radeon I get my console back again.

The only thing I am not getting right is X. Switching to X always makes
a hard freeze. Not even Sysrq works anymore. What I am using is
xlibmesa-dri	4.3.0.dfsg.1-6
xlibmesa-gl1-dri-trunk	2004.02.28-2
xserver-xfree86-dri-trunk	2004.02.28-2
(the last two packages are from http://people.debian.org/~daenzer/

----------------------------------------------------------------

Now my questions:
- Can the missing battery (dis)charge rate be fixed? Is this an hardware
  defect, i.e. the battery does not send the information, or are there
  other reasons?
- Same with the AC Adapter, why does it send no event at all?
- What can I try out to get S2D back again and S2R fully working?

Thanks a lot for any help and I will try to send you all the relevant
information you may ask for!


Best wishes

Norbert
