I couldn't think of a good benchmark but there seems to be something
broken (or I made a stupid error). Simple stuff works:
riff /tmp> egrep 'model|platform' /proc/cpuinfo
cpu model : EV67
platform string : API UP1000 598 MHz
riff /tmp> setenv LD_LIBRARY_PATH /lib/ev67/
riff /tmp> ldd /bin/ls
librt.so.1 => /lib/ev67/librt.so.1 (0x000002000002a000)
libacl.so.1 => /lib/libacl.so.1 (0x0000020000064000)
libc.so.6.1 => /lib/ev67/libc.so.6.1 (0x000002000007e000)
libpthread.so.0 => /lib/ev67/libpthread.so.0 (0x0000020000210000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x0000020000000000)
libattr.so.1 => /lib/libattr.so.1 (0x00000200002ba000)
riff /tmp> ls
#mutt-riff-1000-3777-50# gconfd-thimo orbit-thimo
esrv1000-riff mutt-riff-1000-3777-50 ssh-HadlpA2702
But complex programs fail:
riff /tmp> ldd /usr/bin/gdb
libreadline.so.4 => /lib/libreadline.so.4 (0x000002000003a000)
libm.so.6.1 => /lib/ev67/libm.so.6.1 (0x0000020000090000)
libncurses.so.5 => /lib/libncurses.so.5 (0x0000020000114000)
libdl.so.2.1 => /lib/ev67/libdl.so.2.1 (0x000002000018a000)
libc.so.6.1 => /lib/ev67/libc.so.6.1 (0x000002000019e000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x0000020000000000)
riff /tmp> gdb
Segmentation fault (core dumped)
Exit 139
or
riff /tmp> emacs21
Fatal error (11).Segmentation fault (core dumped)
Exit 139
Interestingly, mozilla 1.7 works fine...

You may be lucky here: after about 3 weeks the Debian Admins finally
got to install the new box goedel.debian.org (Dual EV68). I guess that
in a couple of days it's open for testing. Keep your fingers crossed!
