PC: SONY VAIO 505 laptop

It was OK to use SONY CDROM(PCGA-CD51) for installation of RC2.
But when system was booted after installation, CDROM is recognised as
TOSHIBA CDROM,when mounted cdrom, system told:

[root@localhost /root]# mount /mnt/cdrom
mount: special device /dev/cdrom does not exist

SONY CDROM was OK when on RHL6.2.

Some info are listed below, hope the bug will be resolved ASAP, otherwise
we will face the many,many complaints from SONY users.
