 What kind of CD-ROM is it?  I think the only change that went into the
 cd9660 code in RELENG_2_2 lately is to support mulit-session CDs.  Of
 course, now if your CD is a bogus multi-session, the old code would
 have (wrongly) mounted the very first session of the medium, while the
 new code might complain about a non-ISO9660 filesystem in the current
 (i.e., most recent) session.
 
 Does it work if you ``mount -o -s=0 -t cd9660 /dev/cd0a /mnt''?  (This
 forces the mount of the very first session, like it was the case
 previously.)  If so, can you analyze the situation further (like with
 `cdcontrol info')?  If all else fails, i'd be interested in the CD-ROM
 medium to debug the situation.

 Never trust an operating system you don't have sources for. ;-)
