wm(4) misreporting PCI bus properties

[Matthias Scheler <tron%zhadum.org.uk@localhost>]

        Hello,

my ULTRA60 (running NetBSD/sparc64 5.99.41) reports its Intel Gigabit
ethernet card like this:

wm0 at pci1 dev 1 function 0: Intel i82540EM 1000BASE-T Ethernet, rev. 2
wm0: interrupting at ivec 0
wm0: 32-bit 66MHz PCI bus
wm0: 64 word (6 address bits) MicroWire EEPROM
wm0: Ethernet address 00:07:e9:**:**:**
makphy0 at wm0 phy 1: Marvell 88E1011 Gigabit PHY, rev. 3

What puzzles me is why it claims that it is using a "32-bit PCI bus".
The 66MHz PCI slot in the ULTRA60 definitely supports 64-bit. Is that
a problem with wm(4), with the PCI support for the ULTRA60's chipset
or something else?

        Kind regards
