In an ideal world, yes. In practice the #1 problem in semi-embedded projects
are BIOSes not booting from USB disks at all or unreliable. The best joke is
the Insyde BIOS of DT Research and other AMD Geode LX boards. With a
USB keyboard and/or mouse present the BIOS rarely loads more than a few
kB and then gets stuck. Removing all non-boot hardware from the board
allows the BIOS to usually load multiple MB from the USB HD / stick fine.
(Notice the level of fuzzyness in the above sentence :-)

Lucky you if USB boot works for you that often :-)

PS: The Zip geometry hacking is also described in the syslinux README,
I'll implement it in the iso2stick scritp in T2 as soon as I find a minute.

Yours,
