	Yes, I had a "safe" kernel around (the Debian install kernel),
and the problems are exactly the same. And I believe that all extensions
are in there (Joliet, ISO9660).

	Interesting remark... Of the strace output, I can find about 500
calls to the locale library... The offending bit seems to be here...

stat("/sbin/mount.iso9660", 0xbffff9fc) = -1 ENOENT (No such file or
directory)
rt_sigprocmask(SIG_BLOCK, ~[TRAP SEGV], NULL, 8) = 0
mount("/dev/cdrom", "/cdrom", "iso9660",
MS_RDONLY|MS_NOSUID|MS_NODEV|MS_NOEXEC|0xc0ed0000, 0x805dbf8cdrom: open
failed.
) = -1 ERRNO_123 (No medium found)

	This file, /sbin/mount.iso9660 isn't present here. However, this
might be irrelevant, as mounting a MS-DOS partition looks for a similar
file in /sbin which doesn't exist either, but mounts the thing.

	I suspect a hardware problem, but I haven't open this ocmputer
in _ages_, and it hasn't even been moved arond... Obviously, connectors
are not what they used to :-)

	thanks anyway,
	José
