no console with ACPI

Yesterday I've upgraded a RELENG_5 box to RELENG_6. It is running on
Epox 8KHA+ mainboard. For a reason unknown to me ACPI was disabled
on the installation. Once upgraded to RELENG_6 I have tried to enable
ACPI, but a strange problem arose: when booted with ACPI the box
did not have console. As soon as kernel boot finished, no new lines
were printed (but kernel log messages did appear on screen). However,
the syscons driver seemed to be working: ScrLk switched cursor on/off,
attempts to switch to another vty produced beeps, Ctrl-Alt-Del rebooted.

This is how boot looks with ACPI (no sc0 in dmesg!):

It is possible to login to the box via ssh and see that the boot process
runs to the completion with no problems.

This is how boot looks w/o ACPI:
