Dual PCI busses should run fine with 2.0.x kernels as they locate PCI devices
using the PCI BIOS which of course should handle the dual bus case. Since 2.1.9x
we try to access the hardware directly in order to circumvent PCI BIOS bugs.
Anyway, in 2.0.x /proc/pci will show only the first bus.

Is anyone maintaining the PCI Howto these times?

If you will have some free time, can you also try running the first 2.1
kernel Linus releases (containing the dual PCI bus patches) and send me
all PCI-related boot messages and output of `lspci -vvx'? I'm interested in
whether does it work on the Dell server or not...
Have a nice fortnight
