Odd ifconfig output

Hello all.

We have two PE 1950's with Broadcom Gig networking.  One is giving
strange output in terms of the device name.  The OS is CentOS 4.4 with
latest updates applied for both.

dmesg output (detection seems to be normal):
CPI: PCI interrupt 0000:09:00.0[A] -> GSI 16 (level, low) -> IRQ 169
divert: allocating divert_blk for eth0
eth0: Broadcom NetXtreme II BCM5708 1000Base-T (B2) PCI-X 64-bit 133MHz found at mem f4000000, IRQ 169, node addr 0015c5f189f2
ACPI: PCI interrupt 0000:05:00.0[A] -> GSI 16 (level, low) -> IRQ 169

Driver:
The bnx module is loaded.

<snip>

eth1 is configured to not start at boot.  When I do a manual 'ifup
eth1', it adds this line to dmesg:
  bnx2: eth1: using MSI
And then ifconfig -a shows it as being named eth1 as expected.

1) Has anybody seen this before?
2) Any other comments?  I don't expect this to be a problem, it's just
something new that I had never noticed before.
