yeah, i've installed from cvs yesterday, but no go ... i think that
documents a little old, as the gnomad2v2.5 rpm gives all the
functionality of the cvs now anyways ... i'm almost positive that this
is entirely an issue with the planetccrma kernel (when i boot into the
stock fc2 kernel, my irq's are fine, and so is gnomad2).

ok, i'm downloading this now with apt - a couple of questions though -
is it only the alsa-module that i need to install to go alongside this
kernel? will it use the jack and other stuff i already have installed
for my previous ccrma kernel (as well as realcap)? 

on a short positive note, i have been able to get my nvidia card working
with this version of the driver: 


> NVIDIA-Linux-x86-1.0-6106-pkg1.run

is that the same one that you said you were using? in any case this brings up another 
question - i'll probly need the source code for that planetedge kernel to compile the 
driver module, but i couldn't see it listed in apt ... will i need it to compile the Nvidia driver?

ok, i'll check this out ... keep getting confused between apic and acpi
(so there IS a difference!) ... but, yeah - i don't hold much hope here,
i'm more hoping that the later kernel will sort it all out :|

yeah, linux is fun, but a pain also - dammit, i just want to USE my
computer :)  but, it will all be worth it if i never have to boot into
windows again!!!!

as for your help - you've been an absolute hair-saver!!! even if things
don't resolve on this one, it's sure a lot better to have someone
helping than for me to just go quietly insane :)

thanx again, and i'll let you know how my final attempts pan out ...
