added opensimpad-2.4.27-vrs1-pxa1-jpm1 kernel. This contains the

following new patches over 2.4.25:
- simpad-proc-sys-board.patch (/proc/sys/board patch from Till Harbaum)
- simpad-serial.patch (DTR/RTS/CTS support patch from Till Harbaum)
- mppe-20040216.patch (add MPPE encryption for PPP)
- 2.4.27-mh1.patch (bluetooth patches from Marcel Holtmann)
Common patches were placed in the "opensimpad" directory.
