[HD64461_PCMCIA_driver] - Shared IRQ lines / Segfaults

Greetings,

Driver detects card insertion / ejection and sets power properly. The mapping looks resonable also compairing to a working 2.6.17 driver.
However when manually modprobing drivers I either get a segmentation fault or problems with IRQ shared lines.

Any suggestesions?

Best wishes
Kristoffer
