Could you please send me the kernel command line with and without using
the space (e.g.  dmesg | grep "command line") - i still don't see what
this should be good for.  BTW no need to give root= in OSLoadOptions,
you can use OSLoadPartition instead.

It seems the space in the PROM for OSLoadOptions is quiet limited. The
space available seems to differ between different PROM versions
though(see the HOWTO, it's in there).

Doesn't make a difference. ECOFF is just a save bet.
