Insert boot.img disk boot on a system with only a propietary cdrom interface. Select Other CDROM. The driver list is _empty_ selecting next loads a scsi driver ?!!! Loading the driver disk doesn't help.

This is still there in beta3, I just managed to build my own working driver disk, but now I'm bitten by bug 13094. this is sorta making it impossible to install GRRR!
This is fixed internally -- I can give you a new loader that supports driver disks if you like, but you'll have to assemble your own boot image. Fwiw, 13094 is fixed as well.
