Modified Files:
        src/sys/arch/i386/pci: glxsb.c

Log Message:
glxsb(4): Don't use prev msg's last block as IV for next msg in CBC.

This violates the security contract of the CBC construction, which
requires that the IV be unpredictable in advance; an adaptive adversary
can exploit this to verify plaintext guesses.

XXX Compile-tested only.
