AlphaServer does not start without keyboard and bug with KVM

[DEMAINE Benoit-Pierre]

I have two AS1200 and one AS4100; all have this problem: when connected
to a KVM (trendnet TK-801R) ... in the best case, they dont detect KVM,
and, do not send console to VGA (i assume the system defaults back to
serial).

In a worse standard case, AS1200 dont boot at all.

In critical case, AS4100 dont boot, and make the KVM crash: i cant
switch the active port any more, unill compleet reboot (this requires to
unplug all 16 PS2 cables at the back and the PSU).

Is it known that AS dont mix well with KVM, or make them freeze ? is
there a SRM variable i can play with to make the machine boot even when
no keyboard detected ?
