I'm working with a fairly new machine running rhel4u3, 
and for some reason only 2 out of 4 broadcom nics are
named correctly. I.e. during boot it shows them all named 
correctly:

eth0: Tigon3 [partno(BCM95704A41) rev 2100 PHY(serdes)] (PCIX:133MHz:64-bit) 10/100/1000BaseT Ethernet 00:14:5e:4b:5a:16
eth1: Tigon3 [partno(BCM95704A41) rev 2100 PHY(serdes)] (PCIX:133MHz:64-bit) 10/100/1000BaseT Ethernet 00:14:5e:4b:5a:17
eth2: Tigon3 [partno(BCM95704s) rev 2100 PHY(serdes)] (PCIX:133MHz:64-bit) 10/100/1000BaseT Ethernet 00:14:5e:3f:56:04
eth3: Tigon3 [partno(BCM95704s) rev 2100 PHY(serdes)] (PCIX:133MHz:64-bit) 10/100/1000BaseT Ethernet 00:14:5e:3f:56:05

but for some reason eth2 and eth3 are named dev22358 and 
dev6737. Any ideas why this might be?

I could probably fix it by a simple rule looking at SYSFS{address}
for these two interfaces, but it looks like something must
be wrong with udev here.. ?
