This is really a problem and Mike Sweet is not willing to fix it, as he 
supports only PostScript printers and CUPS Raster drivers and no 
Ghostscript-based printer support. The problem occurs for all PPD files 
which take application/vnd.cups-postscript as input format, also if the 
input is passed through a filter.

Do we need to maintain a fork of CUPS for Linux and Unix environments 
which use Ghostscript or in general for better support of non Mac OS X 
systems?

I have answered the e-mail and I will do at least work on bugs in the 
CUPS Raster output device of Ghostscript until we find another 
maintainer. It seems that Mike Sweet is no concentrated on the Mac OS X 
parts of CUPS (Mac OS X does not use Ghostscript). For using CUPS with 
Ghostscript we are on our own now.

I told in the work plan that for KDE the same has to be done and so we 
need the same amount of work, and a person who does the work. This 
person needs the same amount to be paid as Lars needs for his GTK work.

I agree with that. Currently the PPD matching is done by the printer 
setup toools and each tool does it on its own way. Best would be to have 
the matching algorithm in the CUPS library. Another reason to fork CUPS?
