I've just checked a small backlog of fixes into GIMP HEAD's PSD loader. Quick testing (i.e. whether it compiles :() from someone with HEAD would be welcome, since I guess we're getting close to GIMP 2.0.
I'm also looking for someone who wants to actively maintain the PSD loader, since after six or seven years I'm sick of the sight of the ugly thing, ermmmm, I mean I don't have the time/tools any more. :) You'll need a fair corpus of PSD files from various Photoshop versions to check for regressions against (regressions are easy to introduce in some PSD files while 'fixing' others, and that's not good).
