I changed so that the Makefile in /usr/src/linux said -O6 instead of O2, and 
the arch/i386/Makefile so that the test for 4/5/686 (in my case 686) to have
-m486 changed to -mpentiumpro -march=pentiumpro.

Then I put the path to pgcc/egcs-gcc first in my PATH and did make as usual.

Dunno if -O6 is "best", "recommended optimizer option" or anything else, but 
it worked fine for me.
