As a data point, I have been trying to get some 16-bit PC cards working
on a Thinkpad T60 with 5.0_RC1. So far as I can tell, adjusting
RBUS_IO_BASE can help.
RBUS_IO_BASE = 0x4000 # default, does not work
RBUS_IO_BASE = 0x0a00 # works.
but there is more than that, because although just adjusting the base
downwards made the 16-bit cards work, at least one 32-bit card that I have
(a USB2.0 card I think with VIA chips) caused a panic on insertion but I
didn't write the reason down
I don't understand enough about rbus to say if a better base value would
be better, and if anybody had the knowledge to fix it for 5.0 that would
be really chocolateworthy.
 I have a CompactFlash, a wi(4) and a bt3c(4)
 It uses a TI PC1510 PCI-Cardbus bridge.
 I haven't worked out how to make the message buffer persist through a
reboot on this machine yet
