Where's stderr? vc1?

By this opportunity I also took the latest bf's Adam told me to take
(3.0.21.0.1) from #http://people.debian.org/~aph/boot-floppies-woody/disks-powerpc/current/#.

Ok, I've now ran the system using debug=mem.  Well, I don't know if this has
been the right thing, as Chris pointed out with

Unfortunately, this mail arrived after I have done the testing.

But I will do another run with the command supposed above.


For the Amiga spcialists, my boot command went as follows:

bootstrap --apus -v -k apus/vmlinuz-2.4.17-apus -r apus/images-1.44/root.bin
debug=mem root=/dev/ram video=pm2fb:mode:1024x768-75

It gave me the following output, which I personally consider not very useful,
as I can see no significant messages. As a side effect, nothing has been
printed on vc1 during startup, but I assume this was caused by redirecting the
output to ram by debug=ram.

I wonder that there is no debug output at all, as I thought debug=xxx would
also raise the debug level, as a simple 'debug' does.

Btw: the MAC-Address hiding was done by myself in this email.. So, no kernel error
here!
