Arrgh, you are right.  I know you solved it already, but for the record 
I oversimplified:
   (gd->baudrate / 2)
should have been:
   (gd->baudrate * (MODE_X_DIV / 2))

WRONG:
+	return (CFG_NS16550_CLK + (gd->baudrate / 2)) /
+		(MODE_X_DIV * gd->baudrate);

should have been
+	return (CFG_NS16550_CLK + (gd->baudrate * (MODE_X_DIV / 2))) /
+		(MODE_X_DIV * gd->baudrate);

Sorry,
