Subject[Patch] DVD bugfix in ide-cd.c

This is a small patch to Linux kernel 2.4.1 that fixes a problem with
DVD playback in OMS (Open Media System). With the stock 2.4.1 kernel
OMS will only play up to a certain point on the DVD before it complains
about no more data left on input (basically read() returns 0). This
patch reverts a change between 2.4.0 and 2.4.1.
