My explanation about the graphical/text commands applies to driverdisk
as well.  It's processed by loader, and loader does not understand
%include.  The good news is this is fixed in F15 (therefore, RHEL7 -
yow!), the bad news is I'm not going to be able to backport this fix to
RHEL5 or RHEL6.  It's just too invasive.
