I'm having the same issue with the same Inspiron 1525. I have also tried booting with mainline 3.14.1{,2}, but the issue is still present in these versions. I haven't tried 3.15rc as of yet since the Broadcom wireless kernel module fails to build with it.
I just tried, however, running the 3.11.0-20-generic kernel which is a leftover on the disk from the 13.10. With this version, I have to admit, resume from suspend works just fine.
