I have a 80486DX with vesa local bus video card running Solaris x86 version 2.5.1 just fine. It is incredibly slow as you might guess but I keep it around in case I might ever need it for compatability testing. Many of the video cards listed as Sun-approved for Solaris 2.5.1 were VLB cards, and I can't recall that there ever was a VLB chipset for the Pentium. >This is why it's indeed more appropriate to use >-march=pentium on Solaris x86, but not because of -586 suffix in >assembler module names.
