Oops! Ricoh 5c478. I will post complete dmesg when I get the machine
back in the same place as a working Ethernet card. I added debugging
printfs, and the `reset legacy m ode code' for the Ricoh chips is
getting executed when the pccbb is attached. But by then, a pcic0 at
the legacy ISA addresses has already been attached.
Commenting out the 'pcic0 at isa' line seems to help: scanpci -v shows
sane data for the pccbb when the laptop goes multi-user.

On this Vaio, Uchiyama-san's patch puts all devices not configured by
the BIOS at IRQ 9. I ont know if that really works; it seems to mess
up the suspend/resume processing.
