All sorts of miscellaneous information about the system, including kernel config file and bzip2-compressed kernel.debug, is available online at: http://bling.properkernel.com/freebsd/ The onboard VGA presents itself as follows: none6_at_pci8:12:0: class=0x030000 card=0x34398086 chip=0x47521002 rev=0x27 hdr=0x00 vendor = 'ATI Technologies Inc.' device = 'Rage XL PCI' class = display subclass = VGA Any ideas?
