UML and installing sarge from iso

[Benedict Verheyen <benedict.verheyen@sjki.be>]

Hi,

i have installed several sarge instances in UML via debootstrap. Now i 
wanted to try it once via the netinst iso.

The problem is that my cdrom isn't detected and need to abort the 
install. This is the line that i'm using to start the UML

./vmlinux.2.6.9 devfs=nomount load_ramdisk=1 ramdisk_size=30000 mem=128m 
initrd=initrd.gz root=/dev/ram0 ubd0=rootfs_sarge 
ubd1=sarge-i386-netinst.iso ubd2=/dev/cdrom eth0=tuntap,tap2

This starts the install but it can't detect the cdrom device
I then made sure i mounted the sarge-netinst iso from the cdrom and then 
in the startup sequence i could see that all 3 ubd's where detected 
however the install programs still insists that there is no cdrom device.
If i check with console in the install sequence i see 3 devices inside
/dev/ubd so the start sequence worked.

How can i make sure the cdrom is correctly detected ?
