Annoying problem (Debian Woody)

[<mr-...@li...>]

So...
I finally installed everything, but after booting the system does a sort of
screen cycling which makes the whole thing quite unusable.
I first thought it was a problem with the blanker, but then realized there
actually are 3 screens that get cycled (the main one and two black ones).
This happens both with 2.4.13 and 2.4.9 (2.2.10 does not boot a full
installed sys).

distro:
    Debian Woody 3.0 PPC (6 CDs)

this is the bootstrap line:
    bootstrap --apus -k vmlinuz-2.4.13-apus root=/dev/hda3 nobats
video=pm2fb:mode:800x600-60 video=amifb:vga video=map:0 debug

during debian setup I set XF to use fb driver (if it somehow matters)

my config:
    A1200 BPPC603e+@200MHz/040@25MHz BVision PPC

notes:
    last task launched before it starts screen cycling is gdm
    I am in runlevel 2

I use lha v2.1 (latest version) which should support lh6 compression, but it
won't unpack kernel-image-apus_2.4.17-3.lha anyway. I guess it has
something to do with lha's bugs with OS3.5
