Subject: yenta irq disabled on IBM X20 with dock

I have a IBM X20 laptop. Works fine without the dock (2 yenta ports with 
Ricoh chips). However, when I power it up in the dock (Type 2631), there 
is a problem with additional yenta ports in the dock (TI ones). The 
disable the IRQ and also kill a USB port (the probable reason behind the 
USB messages, but maybe it's unrelated since the USB messages start 
before the IRQ message). Other than that it works fine in the dock.

Tested with 2.6.17 and 2.6.18-rc2.
