64bit PCI problem (hamachi)

[Toshinao Ishii]

Hi.

I've setup driver of hamachi on Linux/Alpha v2.2.5 on
a 164SX and tried two versions of AlphaBIOS v.5.62-1
and v.5.66. The G-NIC II card is installed in a 64bit
PCI slot.

With older BIOS(5.62-1) driver seems to work correctly as
an 32bit/33MHz PCI device.

With the newer BIOS(5.66), Linux recognizes the card as
64bit/33MHz PCI device but there exist "wicked" problem
and the machine cannot communicate to other machines via
G-NIC II.

Here's logs of driver. 

I'd appreciate advices on this problem.
