Sorry - I'm not seeing issues on either ia64 or parisc 64-bit systems.
But I'm only using HP 100BT cards (4-port, occasionally variants of
single port cards, and built-in on parisc workstations/servers).

2.6.12-rc1 bits seem to work fine on a500 (aka rp2470).

Are there any config option differences? 
e.g. MWI or MMIO options enabled on 64-bit but not 32-bit?

You'll have to add printk's until you can sort out why the MII transceiver
isn't responding. Odds are 64-bit code runs faster than 32-bit on
the same machine (more registers or something).

Interesting My source tree says:
#define DRV_RELDATE     "December 15, 2004"
(same version # though)

HP is using exactly this chip. Difference seems to be with the phy/MII.

ISTR to remember submitting a patch so additional data
gets printed in tulip_stop_rxtx. Here is a reference to the patch
but I don't think it is relevant to the this problem:
