The post-install script should've chowned the mysql log files to mysql. Hm,
are the /etc/passwd and /etc/group files in the chroot set up OK? I know, you
probably checked that, but you didn't say anything about it.

Yeah. And if that gives you no useful info, there's always the nuclear
option: "strace -ff /etc/init.d/mysql start > strace.log 2>&1" . That'll
produce a LOT of output, but somewhere within the last ~2000 lines of the
file, there should be something like "open("/usr/lib/mysql/something") : -1
ENOENT (no such file or dir) " that will a) not exist b) be completely vital
c) not be in any error message that gets reported. BTDT, with Orrible.
Also also, if you're using InnoDB, and you copied the MySQL data dir from a
data dir that was being used on another arch (like a 64-bit MySQL data dir
being copied to a 32-bit data dir), then make sure you don't have the old
ib_logfile* files sitting in the data dir. *That* will make 5.0.51a fail on
start with really confusing/stupid/pointless error messages. At least it did
the last time I tried that.
