alsa-driver-1.0.11_rc2 won't build on sparc boxes, it complains about CONFIG_PM_LEGACY being unset, and that's a non-existant option in sparc kernels. Frankly i couldn't care less, kernel builtin drivers have proven to be a better choice for us since they're updated more often by upstream sparc devels.
Seems no one will fix it, so i'll close as WONTFIX. Pity, i soooo love alsa-driver ;-)
