Problem with Wifi card in 2.6.14-rc1

[Larry W. Finger]

I have been using a Linksys WPC54G wifi card with ndiswrapper since 
2.6.5. When I downloaded and built 2.6.14-rc1, the card no longer 
works. The problem is the same with or without "route=pcirq". One 
thing I noticed is that the memory assigned to the PCI system in 
general, and the cardbus bridge in particular has changed. The 
differences between the 2.6.13 and 2.6.14-rc1 output from dmesg that 
seem to be important include the following:
