It appears that not all systems export 32-bit video modes through the VESA BIOS, even when they exist. Accordingly, I have revamped the graphical menu to support 16- and 24-bit modes as well (with 24-bit modes preferred; I suspect they will be slightly faster than 32-bit systems due to smaller I/O overhead.) As usual, testing releases are available from: ftp://ftp.kernel.org/pub/linux/utils/boot/syslinux/Testing/ -hpa
