Quad-port GigE NIC

[Arrigo Triulzi]

Does anyone have good experiences with a low-profile PCI Quad-port 
adapter under OpenBSD?

I've found the following which appears to use a Broadcom chipset (bge*):
   Interphase SlotOptimizerTM 554GB PCI/PCI-X Quad-Port Gigabit 
Ethernet Adapter

I would greatly appreciate any recommendations for low-profile 
Quad-port cards which are known to work on OpenBSD (this one needs to 
go in the half-height PCI slot of an HPQ DL320G3).

Thanks in advance,

Arrigo
