I built kernel with the OPTION i386, I486, I686 removed from the conf file.
Using: gcc version 2.95.3 20010125 (prerelease)

   cc -march=i586  -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes\
     -Wno-uninitialized -Wno-format -Wno-main -O2 -nostdinc

Useerland, X4 work fine.  It is P5, 40M.
