Hi! Sorry that I didn't reply to the original post directly, but I 
subcribed only today.
I applied the patch to my kernel (gentoo-dev-sources-2.6.0-beta11-r2), 
and behold!, my resource starvation problems (RequestIRQ: resource in 
use) were gone. I'm using some cheap atmel based wlan card by Sitecom.
If i can provide some more debug info or do some testing other than 
installing and using the patch, please tell me.

Some info:
