wow... I also thought this must have been fixed already but I didn't find a
message saying so, nor did I see a patch for it so I concluded ethtool was the
way to go.

yup:
dom0:
* running xen-testing from staging, kernel 2.6.32.19 with pvops
* network interfaces: peth0, peth1, ppp0
* bridges: eth0, eth1
* local net is on bridge eth1 with domUs connected there
* internet is on ppp0
domU:
* running PV-GRUB, kernel 2.6.32.19 as above, but stripped down to
the bare minimum
* only one network interface, dhcp to dom0
relevant domU config:
kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz"
extra = "(hd0)/boot/grub/menu.lst"
disk = [ 'tap2:tapdisk:aio:/..../root.img,xvda1,w',
'tap2:tapdisk:aio:/..../var.img,xvda2,w' ]
boot='c'
sdl=0
vnc=1
vncunused=1
stdvga=1
vif = [ 'mac=...., bridge=eth1' ]
grub menu.lst:
title vmlinuz-2.6.32.19-domU
root (hd0)
kernel /boot/vmlinuz-2.6.32.19 console=hvc0 root=/dev/xvda1 ro
If I leave the -K tx off out then I won't even get a dhcp connection in domU.
And btw, vnc doesn't work either, despite the vnc=1. There is no open port, no
idea why yet. Only xm console is available. If I start a domU with HVM it
works.
Here's xm list --long:
