So you chainload SeaBIOS, and try to boot the bsd.rd and it don't show nothing? Your conclusion is that it's because don't have framebuffer? I don't know exactly how is the boot process on OpenBSD (although I use it daily), but I don't think that it require framebuffer to boot. What do you are using to boot? A plain snapshot of install57.iso burned on some CD-ROM? You tried the pxeboot? If nothing works, you could try compile with aperture driver disabled: http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man4/xf86.4?query=xf86 And, reduce the secure level: http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man7/securelevel.7?query=securelevel&sec=7
If not working, try the openbsd-misc and request some help (please, send some dmegs and dmidecode/biosdecode logs). Regards, --mutus
