You seem to be trying various memory address ranges less than 0x1000,
which are not suggested anywhere, since these overlap with the bottom
4K of system RAM.

Please explain this! You're saying that you have another PCMCIA card
that does work in the problem machine?

These memory regions are all completely bogus. I think they must have
been intended to be IO port ranges. Remove them and restore the
original 0xc0000-0xfffff range.

The PCMCIA-HOWTO also suggests disabling BIOS shadowing as sometimes
being a solution to these problems.
