Description
Currently ttya and ttyb are the only ttys, which are allowed to be a console device.
This is a problem for none-SUN machines like SuperMicro MB X8DAH+-F (WPM450 BMC) driven ones, because here IPMI SOL is only possible, if the related BMC port is set to 0x3e8 (ttyc/COM3).
bdha found a workaround by attaching a "VT" aka ttymon to the related tty (e.g. ttyc) so that IPMI SOL works, but of course this has nothing to do with /dev/console ...
As far as I can see, a fix involves the following files (and some related includes), only:
http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/i86pc/boot/boot_console.c
http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/i86pc/io/consplat.c

Good news there is now a webrev available for those of us that absolutely need "ttyc" prepared by Gary Mills on 2012-Feb-14 located at http://cr.illumos.org/view/lsy0hhs4/illumos1469/ .
It works for me in a nightly build (SuperMicro X9SCA-F), but please note there is still a review process going on and the code may be refactored prior to an RTI (refer to: http://comments.gmane.org/gmane.os.illumos.devel/6059 for discussion and details on how to use it e.g. grub and ipmitool ).
