Sound (and wireless) on new Presario R3000

It is confirmed that wireless and sound have an IRQ conflict. If i 
configure modprobe to load atiixp-modem driver (which doesn't do good 
for sound), then i can get wireless to work, and if i use atiixp driver 
in modprobe, then i can have sound in xmms (the rest still doesn't work 
well (see below)), but can't have wireless. Moreover, in the first 
scenario, trying to use sound (even xmms) causes wireless to stop 
working until i log out, and re-login The message is:
Listening on Device /dev/pts/3
localhost kernel: Disabling IRQ #5.

The IDE, audio, modem , VGA compatible controller, FireWire, CardBus 
bridge, and  USB Controller  use IRQ 10. Wireless, and again USB 
controller use IRQ 5, according to lspci -v.

My kernel is 2.6.5-1.358.

Sounds like one absence of a suitable sound card driver is causing all 
the grief. There was no sound until i installed the latest alsa-driver, 
and now there is a conflict, because sound ends up using IRQ 5.  It 
actually makes some sense: both modem (wireless), and sound end up in 
IRQ 5. So it appears there needs to be a driver that handles both audio 
and modem sides of the card, for it not to have an IRQ conflict. And as 
far as i see, neither atiixp, nor atiixp-modem drivers meet this 
requirement yet.
This would be my first experience with improving a driver, but any tips 
on where to start improving one of the drivers above would be appreciated.

Thanks,
