Although I didn't have 5.0 on my old laptop (Tecra 8100 - dmesg is on
wiki) it worked fine there with a pre-branch -current. It barely boots now
(and I've wiped the disk) but I can set it up for testing with a bunch of
kernels on CD if required.

32-bit cards seem to work normally with GENERIC anyway and I tried that
CARDBUS config but found no change with the 16-bit ones.
I took the 0x0a00 value from PRs kern/32327 and kern/32328 (and, all over
the internet when searching for RBUS_IO_BASE :), which also suggests
reducing RBUS_IO_SIZE and that worked fine for the 16-bit cards but both
32-bit cards paniced the machine in that case (from "cbb0: <rbus> no bus
I also tried the patch from kern/32938 which Sverre suggested might help
with kern/32328 but that didn't seem to help :)

Mmm, I was blaming the BIOS, thinking that perhaps for 'security' it
blanked memory on reboot (there is a significant pause)
