I've been using pgcc as my primary compiler for several months without problems. Many parts of my system (kernel, libc, binutils and many applications) are pentium optimized. I generally use -O6 -mpentium options (including compilation of kernels). I haven't noticed any kernel oops, or
anything like this (in stable kernels).

Unfortunately I can't give data about speed difference. I haven't measured it. But some applications' speed increases "visually" - no need to measure it ;)
