This smells like a hardware failure.  The PCMCIA drivers are writing
0x68000000 to a register, and it is reading back as 0x680000dc.  Maybe
Windows works because it only writes to this register and never relies
on reading it back.

Just for kicks, you could try editing modules/i82365.c, find the line
that says:

 pci_readl(s, PCI_BASE_ADDRESS_0, &s->cb_phys);

and add right after that:

 s->cb_phys &= ~0x0fff;
