pccardd of 5.1R-p10 not recognizing card(s)

[Jan Stary]

Hello,

I am running 5.1-RELEASE-p10 hapilly on an Acer Aspire laptop,
except for one thing: the pccardd does not recognized PC cards.

I tried ZCom XI-325 and Micronet SP905B. They are both recognized
fine under 4.7, but 5.1 only says No card in database for "(null)"("(null)")

Trying 'pccardc enabler 0 wi0' makes the machine freeze for a few
seconds and respond with

drv wi0, mem 0x0, size 0, io 0, irq 0x0, flags 0x0
pccardc: set driver: Device not configured

and /var/log/messages says

What posiibly can cause this?
What is ISR?

	Thank you
