[ACPI-sppt] System freeze when lid is closed.

My system freezes up if I leave the lid closed on my Dell Inspiron 5100 
for some amount of time.  Sometimes it takes 30 minutes... sometimes a few 
hours.  When it comes back up, I check my /var/log/acpid (showing when I 
closed my lid at 22:34:19, then when I rebooted at 05:07:28):

...snip...
[Mon Jul 28 22:34:19 2003] received event "button/lid LID 00000080 00000011"
[Mon Jul 28 22:34:19 2003] completed event "button/lid LID 00000080 00000011"
[Tue Jul 29 05:07:28 2003] starting up
...snip...

And a corresponding entries in /var/log/messages (entries between the 
times of the above events, when the lid was closed):

...snip...

...snip...

Funny... the battery readback works fine when the lid is open.  Only when 
I shut the lid, do I get this error message (after some indefinite amount 
of time).  And I have to do a hard-reboot (holding down the power button 
until the system restarts).  I've even tried removing "Button" ACPI 
support from the kernel... but get the same results.

For completeness... here's a dmesg output (ACPI relevant stuff only):

My webpage (seems to be somewhat popular lately), outlines how I compiled 
ACPI support into my kernel:
http://cabibbo.physics.wm.edu/computer/inspiron5100.html

I suspect that the DSDT I've used (for BIOS A02) may not be completely 
compatible with the BIOS of my laptop A06.  I've attempted to construct my 
own table... but the Intel instructions (using pmtools and iasl) lead to 
errors:

> ./acpidmp | ./acpixtract DSDT > dsdt.dat 
> iasl -d dsdt.dsl

Argh.  I don't think that my new laptop is a bad character. ;b 

Can anyone offer any suggestions on any of the problems I've mentioned?
