Kernel update breaks Chez Scheme

["Michel Salim" <michel salim gmail com>]

I have Chez Scheme installed from this tarball:
http://www.scheme.com/csv7.0a/pcsv7.0a-ti3le.tar.gz

and it works fine up to 2.6.15-1.2054_FC5 as shipped with FC5, both
the i686 SMP kernel and the x86_64 kernel.

When I rebooted to 2.6.16-1.2080_FC5, though, on both my i686 and
x86_64 machines I now get the following:
(5 #f "invalid memory reference")

I have SELinux set to permissive + targeted, so what change in the
kernel could have caused this? Should I bugzilla this?

Thanks,
