I wanted to see if it'd be possible to PXE boot this baby, so I built a UEFI version of iPXE. Whilst rEFInd finds it and loads it, it doesn't find a network device - I had been hoping it would like my USB ether adaptor :-( Just in case anyone wants to play, grab http://www.zaurus.org.uk/download/toshiba_click_mini_l9w/ipxe_i386.efi and put into /boot/efi/EFI/ipxe/
