Nope, can't do. The delay will only halt the computer some time before it will 
start booting up.  Secondly, there isn't many lines before this, because the devices in the
kernel is told to be quiet, unless there are errors. At the moment I am testing a kernel upgrade
from Suse, but more or less the same things happen. Inserted some -debug option in the scsi module,
and get more info. So, as you did say "take a picture" would be nice - as there are no device that
I can write it to. 

What the kernel loads to ram is: "processor thermal pata_amd sata_nv fan jbd ext3 edd"
Note the use of ext3 instead of volgroups... Here it will time out as it doesn't find any device,
it doesn't find the hard-drive. 

See my inclosed arrows, this was from Fedora.

At "A" the kernel pata_amd is loaded to ram, initialised with latency timer, then the kernel will continue scanning until it find something at "B:", as can be seen - is reporting back what it is. 

At "C" or just below, the device is mapped.  

Now the kernel is scanning and waiting, but at "D:" - it has timed out. Didn't find anything.
The rest is just what the messages from the different routines that it should have followed.

Identical configured kernels, here OpenSuse 10.2 with kernel 2.6.18.2-34 86x64
failed on a kernel 2.6.22.5-282 86x64

Similar to the test I did on Fedora core 6. On Fedora7, Fedora7.9 , as well as the Fedora7-i386,
all seems to do the same. But with Fedora, there was more crazy stuff - touchpad, keys, well..they wasn't much user friendly anymore ! ;)  Wondered if the damn thing tried to bite my hand off ;)

Note - at first it looks like it has a Broadcom 4321AGN Wi-Fi Adapter - but that is false. It is
a 4311 adapter in my case. ( took some work to figure it out )

( some of my attempts with Fedora is at the fedora-laptop-list at redhat.com )
