RE: [Xen-ia64-devel] RE: [elilo-discuss] a patch to make eliloloadanother module

["Xu, Anthony" <anthony.xu@xxxxxxxxx>]

Dan,
As I mentioned before, I haven't tested the patch on xenolinux. Maybe
there is an address collision, I'll take a look at this, make sure it
can boot xenolinux, and send a new patch to you.

Thanks,
Anthony
