Yes it works.  What I just did:

1. downloaded the preview from Remi's link (so I don't have to build the JDK myself)
2. cloned the hotspot-rt repository
3. built a 64-bit VM (because that's the default on my box; I think universal_debug is actually the right target)
4. dropped the VM into the JDK preview

$ java -version
openjdk version "1.7.0-ea"
OpenJDK Runtime Environment (build 1.7.0-ea-b213)
OpenJDK 64-Bit Server VM (build 23.0-b02-internal-jvmg, mixed mode)

No errors with that build on the Seph testsuite.

And a heads-up:  soon we will push changes to HS23 that makes it impossible to drop HS23 into JDK 7.  I hope there will be a preview build of 8 soon.
