Actually, this is desktop with pci-pcmcia adapter card.
I just tried it in my laptop with 64-bit Ubuntu 8.10 and everything
works perfectly.

It waits for 5 seconds according to dmesg, but the result is the same:
card disabled.

The summary of my experiments so far:
everywhere Ubuntu is 8.10, kernel 2.6.27-11

laptop + cardbus + 64-bit ubuntu: WORKS

desktop + pci-pcmcia adapter:
ubuntu 32: WORKS
ubuntu 64: can't upload firmware
gentoo 64 + vanilla kernel can't recognize external box,
disables the card.
