S'OK.  It looked unfinished, but you never really know....

Yes, that's how it usually goes.

Interesting.  Er... which exact version of ipw2200 are you using?  There 
are a fair number of them, some more stable than others.  If it has an 
even number as the last digit, it's stable; odd number is development.  
So you'd want to try 1.1.0 first, not 1.1.1.  I don't know for sure 
what could be causing your access point problems; I haven't used my 
ipw2200 that much.  (No 802.11 at work, and leeching off the factory 
default access point one of my less-bright neighbors set up just 
seems... rude.)

The 2915 and 2200 are similar (but different) and are supported by the 
same kernel module.  Comments on ipw2200.sourceforge.net and the Gentoo 
forums made me feel that 1.1.0 was the right version of ipw2200 to try.

Hm.  This should be 
in /usr/src/linux-2.6.15-gentoo-r7/scripts/mod/modpost if you've 
configured and built a kernel.  And it shouldn't be necessary to build 
this as a separate package; the ibm_acpi module in 2.6.15.6 vanilla 
seems to work just fine on a T42p.  (Your T43 may vary.)

?  If something's built in to the kernel, you can sometimes change its 
behavior with parameters passed on the kernel command line.  Fiddling 
with that won't help the problem that "emerge ibm-acpi" reported.

Useful stuff: tpb, radeontool, xbindkeys, and all the junk 
under /etc/acpi/ .  Note that you may get weird things happening with 
ACPI events; my T42p generates an event of type "button/lid" when the 
lid's closed, but an event of type "processor/processor" when the lid's 
opened.  Weird, but workaroundable.
