CDrom use in 4.0.3

[lazear at gateway.mitre.org]

For various reasons we don't want to convert from 4.0.3 to 4.1, but we
have a Sun CDrom drive that we'd like to use with our Sun 3/60 or 3/280.
Has anyone successfully "imported" the CDrom support in the SCSI driver
from 4.1 into 4.0.3?  Can it be as simple as copying the binary driver
from 4.1 (which we have) and including it in a 4.0.3 kernel?
