Same problem for me with the new Dapper graphical boot menu.
USB keyboard works in BIOS configuration so boot USB support is working.
When the graphical boot menu with installation/memory test etc options comes up the USB keyboard does not work.
I plugged in a PS/2 keyboard and it worked fine.
Once the text based installer was running the USB keyboard worked OK.
I do not have the PC details on me but will append when I get them (PIII 800MHz, Intel motherboard, USB mouse/keyboard combo with Belkin USB KVM switch - works with several other machines with Ubuntu no probs).
