Have a look at "Identifying differences in mRNA expression by 
representational difference analysis of cDNA", Hubank & Schatz,
NAR Vol.22 No.25 p.5640 (1994).
This method involves multiple hybridizations and amplifications to
end up with fragments of cDNAs present in the tester but not in the driver 
or beeing present in different amounts.
(I didn't yet test it myself.)
