Nice that you found that. And you are correct: that is the root of the
problem. The first relevant error in your syslog is:
Apr 26 20:21:26 base-installer: Using CD-ROM mount point /cdrom/
Apr 26 20:21:26 base-installer: Unmounting CD-ROM
Apr 26 20:21:26 base-installer: Waiting for disc...
Apr 26 20:21:26 base-installer: Please insert a Disc in the drive and press enter 
Apr 26 20:21:26 base-installer: Mounting CD-ROM...
Apr 26 20:21:26 base-installer: E: Failed to mount the cdrom.
Apr 26 20:21:26 base-installer: error: error while running apt-cdrom

I have patches ready to fix all the errors and I will commit and upload
them later today.

However, I am still very much confused as to _why_ the mount fails. Do
you think you could get an strace for it?

The rough procedure to get the strace would be something like this:
- proceed with the installation until the kernel installation error
- switch to a debug shell
- chroot /target
- wget <strace package, for example [1]>
- dpkg -i strace_4.5.15-1.2_i386.deb
- strace -f -o apt-cdrom.strace apt-cdrom add </dev/null

And then mail the apt-cdrom.strace file to this bug report (gzipped!).
