ok, what's your CD-ROM attached to?
is it an IDE or a SCSI CD-ROM?
If scsi, which HBA is it connected to?
And have you compiled kernel support for that HBA?

The major=0x48 is really 72 which is some exotic hardware called
"Compaq Intelligent Drive Array". Do you have an instance of such hardware
in your machine?

And why are you passing "enableapic" boot parameter if it doesn't exist?
(unless it is some new 2.5.x thing)

I assume you are booting Linux 2.4.18, because that is what the patch was
supposed to apply to.
