Ah - thanks for your answer. I didn't set the XB-Subarchitecture field,
because it wasn't set in the control file. In case of the newworld example,
I can't find where powermac_newworld comes from. What to do if I only
want to have this loaded when using the pseries flavor added by me in
the linux-kernel-di-powerpc's kernel-versions file?


While looking for the way to set the correct subarch, I found that in
base-installer's postinst, line 438 the CPU variable is filled by:

CPU=`grep '^cpu[[:space:]]*:' /proc/cpuinfo | cut -d: -f2 | sed 's/^ *//; s/[, ].*//' | tr A-Z a-z`

The following case doesn't seem to work with more than one CPU. In
my case CPU contains "power4+ power4+".

CPU=`grep '^cpu[[:space:]]*:' /proc/cpuinfo | cut -d: -f2 | sed 's/^ *//; s/[, ].*//; q' | tr A-Z a-z`

fixes the problem.
