Perhaps you could try using cdrtools 3.01a17 and Syslinux 4.06 from 
"Slackware -current"? Or even Syslinux 4.07 official archive? I don't 
really know if it would actually make any difference for you, but 
there were patches related to isohybrid introduced after Syslinux 
4.05.

Or, wait for someone else to provide some other, more specific 
suggestion.
