Linux on a Laptop

[temljrmjrlmr at comcast.net]

Sorry this is a couple of days old but I have been messing with ACPI on 
Thinkpad T20, & T21's  for months and have some observations...

-Tried disabling ACPI to but now I use "acpi=force" and it seems to work 
better ( initialization at power-up below).
-OS is Debian (testing) initially built off Knoppix 3.6 with kernel 2.6 
option booted -  then installed to HD with knx-hdinstall.
Now running kernel 2.6.7 .  In general it works quite well after alot of 
twiddling.  Some drivers updated from the IBM ThinkPad site.  
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4JSQHB 
; I cant seem to find IBM's drivers for Linux on the site now...
-Finally got full functionality from the Mini-PCI modem after loads of 
trouble.
Here is some info from dmesg related to ACPI initialization:

Hope this is helpful - apologies if I revived a thread which was 
gratefully dead...

Apt or dpkg?  Apt is just a front-end for the packaging system, and 
there's a version of apt for RPM based systems.
