Looks OK. Thanks very much.

Cache line size is set to 128.
Latency timer 255 is probably too high if PCI BUS is 33 MHz.

Sigh!! MEM BARs are 64 bit range as assumed by sym.
So, `sym' should correctly deal with on-chip RAM BAR.
It is /proc/pci under Linux/Alpha that lies about the
MEM BARs range.
This should be looked into, since it could well be the
Linux driver that will be confused if the BAR cookies
in the pcidev structure are nor properly set with the
right range bit.
