Re: IBM Thinkpad G41 PCMCIA problems

[Bjørn Mork]

I think I might have a new datapoint to add to this discussion:
I've got a IBM Thinkpad T42 with 1 GB RAM.  Never had any problems
with PCMCIA, but that's probably just because another PCI device has
been mapped into the hole in the BIOS memory map:
