Yes, the vt8235-atapi patch works for me; so did vt8235-dvd, but not vt8235-min.
Mitsumi FX4830T ATAPI CD-ROM, MSI KT3 Ultra2 mainboard (KT333), vt8235.

I modified the patch so that it would apply cleanly to RedHatLinux8.0
kernel-2.4.18-18.8.0 as part of "rpm -bb --target i686 kernel-2.4.18.spec".
The result is attached.
