Well, I see some progress there... Today I was able to do some tests again, 
and I was able to ping -f another box on the same network for some time. I 
tried then csup sources and I got hard hang, again, this time with following 
lines on console:

vr0: PCI bus error -- resetting
vr0: restarting

And no ability to enter kdb, either.
Just for record, I am getting following when kldload'ing if_vr:

vr0: <VIA VT6105M Rhine III 10/100BaseTX> port 0x9c00-0x9cff mem 
0xfceff000-0xfceff0ff irq 18 at device 8.0 on pci3
vr0: Quirks: 0x6
vr0: Revision: 0x96
miibus1: <MII bus> on vr0
ukphy0: <Generic IEEE 802.3u media interface> PHY 1 on miibus1
ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

(one out of four devices shown)

In my eyes, if new vr works for others and no regression was found, it should 
go in. I did not encountered a regression - it did not work with old driver, 
it does not work (yet) with the new... but I hope we can get this one 
working, too...
