pgcc-2.91.51 showed this behaviour for me, too. pgcc-2.92.21 works.
In fact, I'm just running an -O6 amdk6 2.1.131 with no problems
(well at least not ones that wouldn't have shown up on others'
gcc-2.7.2 kernels) so far.
2.91.51 with -O3 is buggy as hell, yes.

Just since a patch to include this in the make *config came up,
I think this should be mentioned as a huge warning in huge,
friendly letters.
