xen & dom0 output in ILO virtual serial port

OS: SLES 10 SP1 (but should be same issue on every linux I guess)

Does anyone know how I can capture both Xen & Dom0 console output on the VSP from an ILO v1.35 (from a Proliant bl460c)?

I've tried several combinations & options of "console and such", so far, none worked. I was able to get Xen-console output only with these options in grub:
root (hd0,0)
kernel /xen.gz com1=115200 sync_console
module /vmlinuz-xen root=/dev/cciss/c0d0p3 splash=0
console=ttyS0,115200 console=tty
module /initrd-xen

Something goes wrong after that in the dom0 and I can't scroll back on the ILO-KVM so I need the dom0 output via serial as well (also because it's usefull for copy-paste). Possibly with a trace if I can get working :-)
