Finally got to compile a working version from this, not sure what was wrong with my previous builds...

I've tested on my X5000, all working good so far, in fact my Soundblaster live sound card seem to like the changes and works without patching the kernel. (Nice)

Not sure when I'll get chance to test on X1000 though.
