You guessed right:

agp0: <VIA 8377 (Apollo KT400/KT400A/KT600) host to PCI bridge> mem 0xe0000000-0xe7ffffff at device 0.0 on pci0
pcib1: <PCI-PCI bridge> at device 1.0 on pci0
pci1: <PCI bus> on pcib1
pci1: <display, VGA> at device 0.0 (no driver attached)
vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0
