Hi again,

thanks to Manuel and Eduardo, I've managet to get a bit further in this
text adventure. :-) Now I have a kernel booting that recognizes the DVD
RAM: 

sd1 at scsibus targ 4 lun 0: <MATSHITA, PD-2 LF-D100, A113> SCSI2 5/cdrom removable
sd1: could not mode sense (4/5); using fictious geometry
sd1: 595MB, 595 cyl, 64 head, 32 sec, 512 bytes/sect x 1218960 sectors


but later during boot, the system hangs: 

...
biomask ca40 netmask ca40 ttymask dac2
wscons: wskbd0 glued to wsdisplay0 (console)
sd1: could not mode sense (4/5); using fictitious geometry
<hang>

<ctr-alt-esc>
db> t			(this is all typed in, addresses omitted)
_idle
bpendtsleep
_biowait
_readdisklabel
_sdgetdisklabel
_sdopen
_spec_open
_match_harddisk
_findroot
_cpu_rootconf
_main

It seems the faked gemometry is a bit strange. The size should be
something at 5.2GB, and two heads. Also, the drive is still printed as
5/cdrom. Plus the hanging when the system's looking for a rootdisk. 

Any clues on how to go on here?  
Thanks a lot!
