What I also forgot to mention is, that it's a SmartMedia Flash Card I have
here, which is told to always identify as a IDE device.

Ohh, that's why lsusb never worked.. but you won't like the current result:

Bus 001 Device 003: ID 046a:002b Cherry GmbH --> Keyboard
Bus 001 Device 002: ID 0451:2046 Texas Instruments, Inc. TUSB2046 Hub
Bus 001 Device 001: ID 0000:0000 --> What the..?

But I'm afraid I broke my SMC, while playing around with my disassembled
T20, since GRUB hangs with 'GRUB _' without having changed anything in the
software. D'oh!

That's why I can't test with 'USB Mass Storage' support in the kernel at
the moment, which would probably uncover the mysterious '0000:0000' USB
device. Gonna try again next week with a new SMC.
