Related to bug #2067, with @cast() now taking a module name argument,
we can fail to process a @cast() if the type named was only defined in
a module rather than core vmlinux. e.g. rhel5 scsi_device, as in the
newly failing buildok/scsi* tests.
So perhaps @cast could grow a search-path facility:
@cast(value, "scsi_device", "kernel:scsi_mod")

Same is necessary for the new rpc code after:
commit fb3b52a7346202fea1905ed680a3256d372a7b03
Author: Wenji Huang <wenji.huang@oracle.com>

PR9871: use @cast in tapset
Rewrite some functions using type casting to
get rid of embedded C code in nfs, scsi, signal,
socket, rpc, task and vfs tapset.
Signed-off-by: Wenji Huang <wenji.huang@oracle.com>
This results in failing tests like:
starting /home/mark/src/systemtap/testsuite/buildok/rpc-embedded.stp
spawn1 stap -p4 /home/mark/src/systemtap/testsuite/buildok/rpc-embedded.stp
semantic error: type definition not found: identifier '@cast' at
/usr/local/systemtap/share/systemtap/tapset/rpc.stp:974:14^M
semantic error: type definition not found: identifier '@cast' at
/usr/local/systemtap/share/systemtap/tapset/rpc.stp:974:14^M
source: rpc_proc = @cast(msg, "rpc_message",
"kernel")->rpc_proc^M
Because on my system sunrpc is compiled as a module.

In the future we may want to expand this to all module-searching components, but
for now I'll work on adding it for @cast.
