Cool. :-)
I've changed things slightly in the latest CD builds for d-i, based on
this and other reports. Instead of using auto mode for graphics, I'm
now forcing 640x480. That's not going to look very pretty, but it
should be guaranteed to work I hope!
If you could test-boot a new CD image for me and confirm that you at
least get into the grub menus, that would be lovely! :-)
