No luck with that either :(

The IPMI serial console works for the BIOS & loader so I guess the comconsole parts work, however the kernel doesn't seem to use it even with '-D -h'.

The uart(4) flags are correct (I believe)
uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 on acpi0
uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0
uart2: <16550 or compatible> port 0x3e8-0x3ef irq 5 flags 0x30 on acpi0
