A quicker solution was to use my flash as a JFFS2 root filesystem (it
was actually quite complicated, because write support in the kernel
(MTD) is broken for the onboard flash chip - well, read it on the
linux-mtd ;) ). I now mount this readonly, and I have a filesystem
without needing to reserve RAM for it - where the initrd resides. So
this is actually a better solution, that utilizes my ressources better. :)

I would like to still found a solution incorporating an initrd, but in
this case only for completeness' sake.

Anybody ideas about how of if to set the following parameters:

root, rootfstype, keepinitrd

and any others needed to use the initrd?

Residual-Data Located at: $01F5511C
loaded at: 00005400 001655BC
relocated to: 00800000 009601BC
zimage at: 008058B0 008C16FA
initrd at: 008C2000 0095D000
avail ram: 00400000 00800000

I'm a bit unsure whether these are good values, or if the place the
initrd is relocated to at loading is actually problematic - e.g.
problematic with regards to HIGHMEM, or end of memory. I have 32MB of
physical mem.

Hope I didn't demotivate anyone to find a solution, though! ;)

With kind regards,
