The X server's driver uses codes (like 0x5c) that it doesn't expect to
ever see as input to encode the 0xe0 0xXX two-byte codes.
We have a KEY_KP_Equal value defined in common/atKeynames.h: 0x76 (+8 = 126).
This conflicts with the value used for <META> in xkbcomp/keycodes/xfree86.
My suggestion would be the following patch for the XFree86 DDX, and
assign <META> to a different value, assign <KPEQ> to 126 in
xkbcomp/keycodes/xfree86, (and make <KPEQ> to a keysym in the appropriate
places).
