Realtek 8168B/8111B PCIe Gigabit ethernet and NetBSD 4.0 i386?

[Carl Brewer <carl%bl.echidna.id.au@localhost>]

I have a new Gigabyte GA-G31M-S2L motherboard with a new realtek 
ethernet chip on board.

dmesg shows :

re0 at pci2 dev 0 function 0pci_mem_find: void region
: RealTek 8168B/8111B PCIe Gigabit Ethernet (rev. 0x02)
re0: interrupting at ioapic0 pin 17 (irq 10)
re0: Unknown revision (0x3c000000)
re0: Ethernet address 00:00:00:00:00:00
re0: using 256 tx descriptors
rgephy0 at re0 phy 7: RTL8169S/8110S 1000BASE-T media interface, rev. 2

And I get a lot of errors :

Apr 26 03:00:16  /netbsd: re0: watchdog timeout
Apr 26 03:00:16  /netbsd: re0: reset never completed!
Apr 26 03:00:24  /netbsd: re0: watchdog timeout
Apr 26 03:00:24  /netbsd: re0: reset never completed!
Apr 26 03:00:49  /netbsd: re0: watchdog timeout
Apr 26 03:00:49  /netbsd: re0: reset never completed!
Apr 26 03:00:54  /netbsd: re0: watchdog timeout
Apr 26 03:00:54  /netbsd: re0: reset never completed!


Is this an unsupported revision?  It seems to work ok roughly 50% of the 
times I boot the box.  The MB manual says it's an RTL 8111C chip.
