I have had the opportunity to install the woody branch on my 7043p-140 a
year or two ago.
AFAIK there is need for a kernel patch to get a loader prompt to setup the
needed kernel parameters (in this case root=<something>)because some PReP
machines have some problems passing the parameters to the kernel. I have
been able to get it installed with help from
http://www.solinno.co.uk/7043-140/ . You can also get bootdisks there. To
get it running with sarge isos someone has to add a boot system to a not
recently used
PPC cdimage.

Can you enter the root option for the ramdisk in the above line when using
a serial terminal?
If yes, you should be able to add the root option and install the system

This one looks like he got the options from "Linux/PPC load" above.

This is the line where the kernel can not mount root, because he does not
know where it is.

I think Leigh Brown, Maintainer of solinno.co.uk, can help us in this one.
He has got his 140 running with sarge since january 2005.
