i'm not sure what causes this no irq errors either.
recently, about a month ago, i bought a Richoh pcmcia 
adapter as well, and have the same error. at first i 
thought it was bios. i change the installation on 
another system with different bios, it didn't work too.
both m/boards did have pci bus v2.2 or higher.

happen that the richoh card is valid for a refund, 
hence i went to get a refund for incompatible reason. 
i realised this Richoh cards seesm to have been revised 
and unable to be used for Wireless cards on Linux.
And it works well on Windows. I find it really strange, 
but i didn't have time to debug and figure more out of 
it at that time.

May be others have similar experience with any recently 
bought Richoh adaptor cards, please share if you encountered 
and fixed it.
