I have a bunch of Sun Fire X2100 M2 which lack PS2 too, but USB keyboard 
is working fine. Did you test it with upcomming 7.2?

Can you explain it more detailed? Do you have model where IPMI card have 
shared NIC port with standard on-board NIC? Intel 5520 Tylersburg based 
Twin servers have IPMI + KVM integrated onboard with dedicated third NIC 
port. May I expect problems or am I save with dedicated port?

There are 4 NIC ports on Sun Fire X2100 M2, where 2 are nVidia and 2 are 
Broadcom (bge). One of those bge is shared with IPMI + KVM, but in this 
case, it works fine for more than year with hw.bge.allow_asf="1" in 
loader.conf. No locks, no packet loss.

What is model number of your servers?

Thank you for your reply
