woody to sarge - where is the new kernel?

[Mario Frasca <mfrasca@zonnet.nl>]

hallo all,

I'm a linux fan since its 0.97 version, but I'm new to the apple world.
  a few months ago I bought a second hand iMac and I'm *very* happy
with it.  obviously, it is a linux-only box!  I chose Debian for its Mac
support.  on pc hardware I'd always used Slackware and update it with
source tarballs.

mario@kruiskruid:~$ cat /proc/cpuinfo
cpu             : 750CX
temperature     : 11-13 C (uncalibrated)
clock           : 500MHz
revision        : 34.21 (pvr 0008 2215)
bogomips        : 996.14
machine         : PowerMac4,1
motherboard     : PowerMac4,1 MacRISC2 MacRISC Power Macintosh
L2 cache        : 256K unified
memory          : 576MB
pmac-generation : NewWorld

at start, I had no internet connection so I asked a friend to burn for
me the full distribution Woody (3.0r2) on 6 CDs.

now I _am_ connected and I updated woody and then upgraded to sarge.

I have the following problems

---1-
my system does not boot any more from hd.  I have to use cd1 from the
woody distribution and then tell the booter to load 'hd:4'.

---2-
I cannot repair the #1 issue.  if I try to remake the boot partition, I
get a silly answer.

kruiskruid:~# mkofboot
ofpath: WARNING: Your kernel is too old for proper support, device may
be innaccurate.

mkofboot: Create hfs filesystem on /dev/hda2? [y/N] y

and nothing happens (I try to boot again, but the system refuses and
grasps to the CD).

---3-
so I thought I need an old ofpath *and* a new kernel and then again the
new ofpath.

--- -
any suggestions?

thanks in advance.
