2.6.31 plus this patch fixed the hang on IDE initialization with the
SIS5513.

That's with my testing mode, I'm rebuilding a kernel and will try some
benchmarks tomorrow.  I've been testing by hibernating to disk,
booting the test kernel with a bad root and resume partition (so if it
worked it wouldn't modify the suspended image), then rebooting to
resume from disk with the good kernel.  That let me more quickly
bisect and test kernels, I just haven't ran this kernel much past the
initialization is all.
