The problem comes from having an 80K video bios (0xc0000 -> 0xd3ffff).
This breaks two things:
1: the default pccard (oldcard) address is 0xd0000 and overlaps with the
rom, which causes pccardd to see garbage instead of the CIS>
2: XFree86 carefully calculates the size of the ROM, and then memcpy's
all 80K of it onto a 64K stack buffer. Sigh.

This is just an expedient hack to get it working for me. It needs to be fixed
properly.
3: NEWCARD doesn't seem to have any way to change the CIS window address.
It merrily maps into 0xd0000 and then explodes in the kernel probe due to
the "garbage" CIS there.
After getting over the initial hurdles, I'm pretty happy with it. It isn't
quite a Dell Inspiron 5000e, but it is close enough.. :-)
Cheers,
