initialize HFC-PCI isdn driver properly on 64 bit

The HFC-PCI driver sometimes doesn't initialize properly on 64 bit. This seems to depend on the mainboard being used and on chance. On my system, a MSI K9A2VM (AMD 780V chipset), it never works; on another system used by Karsten Keil for testing, it fails every 3rd to 5th boot. 

When the initialization fails the isdn module seems to load without problems, but no dialouts or dialins are registered, and an isdnlog running on the device doesn't get anything. 

Karstein Keil provided me with a patch which solves the problem on his and my machine which I attached to this bug report.
