Sorry, but the kernel only recognizes ttya and ttyb (and usb-serial) as 
console= values, not ttyc.

It's been a very long missing feature on Solaris x86, but became less 
important as the number of motherboard serial ports has reduced over the 
years, and ISA-bus serial cards became unusable (no ISA-bus slots anymore).

Can you disable ttya (com1) in the BIOS, and then reconfigure ttyc 
(com3) to have the i/o address and irq which were associated with com1, 
so it looks like com1 (ttya) to the OS? (IIRC, 0x3f8 and IRQ 4)
