I'm almost positive that these are alsa-driver configure errors or omissions. I can't (yet) find a kernel config that will avoid them. The fixes below are harmless, and they will allow you to get the driver compiled.

I recompiled the kernel without SMP support, and as PC-compatible (per
forumjunk at comcast.net). In config.log, vmalloc_to_page shows a warning
starting at line 540. "function cpuid_count causes a warning: pointer
targets in passing argument 4 of 'native_cpuid' differ in signedness".
Since config.long is so long... I posted it here:
