 ttyload has been shown to run on systems running, at least:
 
 - Linux (at least some configs of it -- I'm using a SuSE 6.x box
-  to build it on.)
+  to build it on, with a 2.2.x kernel)
 - IRIX 6.5 (and possibly other versions?)
+- FreeBSD (some version or other, I'm not familiar with their
+  numbering system...  4.4, I think.)
 
 Hopefully soon it will also run on:
 
 - Solaris
-- FreeBSD
 
 Feel free, if you like, to submit patches to add more platforms,
 and please let me know also if it runs unmodified on any other
