Hi.  I'm ressurecting an old thread just to inform anyone who may be
interested that I have finally gotten my SanDisk Cruzer Micro to boot.
 I'm not sure if it was more luck than anything else or what. 
Firstly, I was using syslinux-3.20-pre6 (pre7 wouldn't run on the live
disc I was using) and the mkdiskimage which came with it.  I just used
the standard command "./mkdiskimage -4 /dev/sda 0 64 32" to make the
image, then used "./unix/syslinux-nomtools /dev/sda4" to install. 
Every now and then it doesn't boot unless I take the drive out and put
it back in just after the system has rebooted, but, now it does work.

If anyone is interested, let me know and I can send a clean disk image
for either examination or your own uses if you also have a Cruzer
Micro.  Just bear in mind that it's the 512MB image, so if you have a
1GB or 256MB drive it will end up giving you either a filesystem too
large to work or too small to properly utilize your drive. 
(Compressed the 512MB image comes to about 668KiB, so most e-mails
should accept it.)  It's a full disk image, so you'd just extract over
the whole disk, not just the partition -- this way it includes the
full partition table and all boot data.
