Actually I just put out 0.1.16, which in addition to being noarch, also 
fixed a problem when installing to rootfs on non-lvm partitions.

The other reason I'm replying to this, is the PS at the end about 
syslinux's menu.c32 vs vesamenu.32, turns out to be a result of 
livecd-iso-to-disk using the burning host's syslinux.  I.e. if I burn my 
LiveUSB from centos-5.4 instead of 5.3 or fedora, the grey screen 
bootloader problem doesn't show up.
