ibook2r2 & strange freeze.

Hi all,
I apologize if this is the wrong list to ask my questions...
I don't know if anyone here could have an answer to my problem.
I have an Apple iBook 2.rev2 from last mid year.
I was running almost perfectly one of the Benjamin Herrenschmidt's
2.4.19 kernel.
A few days ago I completely re-installed the beast with the latest
Mandrake PPC 9.1 which is shipping with a non working kernel for those
ibooks.
I then compiled & installed the latest benh stable kernel (2.4.20-ben10)
which is really unstable on my computer when booted with the default
parameters.
When I boot with video=ofonly there are no problem at all (except that
the backlight controller does not work anymore...).
Several other mandrake user owning ibook2r2 reported that their computer
where not stable without video=ofonly.
By unstable I mean that the computer completely freeze during boot time,
around the time rc.sysinit is launched. Unfortunately I'm rather new to
linux kernel so I don't know how to provide more information on the
crash (maybe should I configure the kernel with xmon ?).
In a divide&conquer approach I found that the part of rc.sysinit which
'uploads' the console font to the font layer was triggering the crash.
I then re-installed from scratch everything (because I thought there
could have been a fs corruption somewhere which had corrupted the
fonts), but no chance it crashed again.
I then commented-out this part of rc.sysinit and then I could boot up to
the login prompt.
But the kernel was still unstable, and still froze at completely random
time (mounting a cdrom, vi'ing some text files, rsyncing a kernel,
compiling the kernel).
I decided to have a look to the latest devel kernel (namely
2.4.21-pre7-ben0 and 2.4.21-rc1-ben0) but no chance again, when booted
with video=radeonfb (or with nothing) they're oopsing during the boot (I
can provide more information if needed). With video=ofonly, everything
went smooth.
As I wasn't sure the crash came from my compiled kernel, I also tried
pre-built kernel from penguinppc.org (the following dmesg output has
been taken from this kernel). This kernel was relatively stable with my
modified rc.sysinit, but failed with the original rc.sysinit.
So, what should I do to have a stable kernel with radeonfb ?
Many thanks,
Regards,
Brice
