Apparently, detecting more than 16MB in a PC requires some additional 
code that makes the FreeBSD boot image larger than can fit on one 
floppy. What you need to do is recompile the kernel (see 
http://www.freebsd.org/FAQ/freebsd-faq85.html#85 for detailed 
information on how to do that), and use the entry 'options "MAXMEM=<n>"' 
in your kernel configuration file 
(http://www.freebsd.org/FAQ/freebsd-faq91.html#91 has more information).

Hope this helps. I have 96MB and after setting MAXMEM=98304, all 96MB 
were recognized.
