[CentOS] install from USB thumdrive

Hi all

Is there a procedure to use an 8GIG thumbdrive to copy the centos 5.2 
dvd contents
to the thumbdrive then run isolinux (or something like it) and be able 
to use the thumbdrive as the install media?

Seems like it should work, however my machine only has syslinux not 
isolinux.
yum provides isolinux does not return anything.

Anyway I was trying to get to a point where I can just stick a USB fab 
in a machine,
have the fab setup with the correct kickstart and everything so it just 
installs.
I cant modify a DVD but a fab I could put the kickstart files on and 
nothing to type.
