Yes, and I get a faint sniff from the tone in your email that that may mean Suhosin is never ready for php5.4
One of the developers of Arch Linux agrees:
"The upstream project has become less and less active in the past years. There are certain indicators which make Suhosin an unhealthy open source project: There is still only one main contributor, the development process is mostly closed, there is no public repository for the patch, no bug tracker, the forums are in maintenance mode for years and the latest news entry is from 2007. Of course things might be different in the background, but this is the situation which is publicly visible."
Hence, PHP 5.4 is not coming to Dreamhost in the foreseeable future.
