Missing cardbus label in /proc/interrupts

Missing cardbus label in /proc/interrupts

Seen in 2.6.0-test3's /proc/interrupts:

The cardbus devices aren't listed.  I'm using the network card in one and
the CF card is readable in the other.  This is probably a trivial bug.

I noticed this after several card insertions, so I rebooted the system,
but this seems to be constant.

In 2.6.0-test4, /proc/interrupts:

 11:     195758          XT-PIC  uhci-hcd, 0000:00:04.0, 0000:00:04.1, eth0

The labels are no longer missing, but is this the ultimate designation for
a cardbus bridge?

This should be fixed in 2.6.0-test4-bkcurr as of tonight (they're now
called "yenta".)
