Thanks.

Yes, it does, without any kernel parameters by the way, otherwise I get
serial working but VGA stays blank.
The X server crashes in some I/O port "inb()" command. Seems like the
io permissions aren't correctly passed through or something. (iopl or
ioperm or so) I'll try to debug a bit more later.

Since 3.3.0 was working, I just sticked with that for now.
I am actually using extlinux, but that shouldn't really make a
difference:
LABEL linux-2.6.29-rc1-xen-cs1
MENU LABEL Gentoo + XEN-3.3.0 + 2.6.29-rc1-xen-cs1
KERNEL com32/mboot.c32
APPEND xen-3.3.0.gz --- vmlinux-2.6.29-rc1-xen-cs1.gz root=/dev/vg/root ro nopat
for serial console this (which I only tested under qemu):
LABEL linux-2.6.29-rc1-xen-cs1
MENU LABEL Gentoo + XEN-3.3.0 + 2.6.29-rc1-xen-cs1
KERNEL com32/mboot.c32
APPEND xen-3.3.0.gz console=com1,vga com1=9600,8n1 --- 
vmlinux-2.6.29-rc1-xen-cs1.gz earlyprintk=xen console=tty0 console=hvc0 
root=/dev/vg/root ro nopat
Cheers,
 Christophe
