A kernel from Gentoo's package for the XenSource 2.6.20-xen-r6 sources
(which seem to be end-of-the-line for the separate Xen patches?) has
working net when run with a NetBSD dom0, but has this problem instead:

        madcow dev # date
        Thu Jan  3 16:51:01 EST 2008
        madcow dev # ntpdate pool.ntp.org
        3 Jan 16:51:08 ntpdate[3761]: step time server 69.31.13.210 offset 
14495.938724 sec
        madcow dev # date
        Thu Jan  3 16:51:10 EST 2008
        madcow dev # date 01031951
        Thu Jan  3 19:51:00 EST 2008
        madcow dev # date
        Thu Jan  3 16:51:26 EST 2008
        madcow dev # 

If I could find any way to solve that, I could probably stop bothering to
try to make 2.6.23 work.  Any ideas?
