[CentOS] Installing 6.0 via USB

I'm using LiveUSB-Creator to create a bootable USB drive from 
CentOS-6.0-i386-netinstall.iso, and it gives me an error at startup:

vesamenu.c32: Not a COM32R image

I can hit tab and select "linux" and then it loads vmlinux and the initrd, 
says "Ready", and then just hangs. I'm not sure what's supposed to happen 
next. "vesa" and "rescue" do the same thing.

The error message above apparently is caused by the syslinux in the ISO not 
matching the one that LiveUSB-Creator installs to boot from:

<https://bugzilla.redhat.com/show_bug.cgi?id=662557>

The system has 512 MB of memory. Is that enough to boot the installer?
