cross-installing grub : what next

Hello all,

I've come to creating an image (busybox, kernel, etc.) of which I
THINK it would work, once deployed on my target. I did this using
ptxdist's cross-compilation possibilities. My host system is a i686
architecture, my target is a Geode EmCORE-n511 (so an i586
architecture).

Now I have the next problem, being to cross-compile grub for it, and
to install it on my target hardware (via an image). All of this, I'd
like to continue to do this using ptxdist, preferably. BUT... I have
some questions :

1. would someone have an example (or some useful links) on how I
should do this, continuing to make use of ptxdist ?
2. how can I determine what devicename the CF socket- inserted disk
will have ? I think I should know this for my /etc/fstab ?

Thank you, and kind regards,

PhB
