How did you tell to CUPS that the job is fullbleed? The PPD has non-zero 
borders for all paper sizes.

It seems also that pstoraster or pstops does not supply something useful 
for the "cu[psPageSizeName", as error_log shows the following:

D [15/May/2009:14:39:26 -0700] [Job 383] Setting cupsPageSizeName to 
"74%%BeginFeature: *PageRegion 
10074^D^D^D%%BeginSetup%%EndProlog%%EndResource%rom%Resource/IdiomSet/*/*"...

The name is important to distinguish page sizes with the same dimensions 
but different margins.

> Looking at the fullbleed-bad.txt error log it looks like gdevcups.c has mistakenly declared this a custom paper size instead of the fullbleed 4x6 paper size and thus uses the custom paper size printable margins of "margins[] = [ 0.125 0.125 0.125 0.125 ]" instead of [ 0 0 0 0 ].

Try something like

*DefaultPageSize: LetterDuplex
*PageSize Letter/Letter 8.5x11in: "<</PageSize[612 792]/ImagingBBox 
null/cupsPageSizeName(Letter)>>setpagedevice"
*PageSize LetterDuplex/Letter AutoDuplex 8.5x11in: "<</PageSize[612 
783]/ImagingBBox null/cupsPageSizeName(LetterDuplex)>>setpagedevice"
**PageSize A4/A4 210x297mm: "<</PageSize[595 842]/ImagingBBox 
null/cupsPageSizeName(A4)>>setpagedevice"
*PageSize A4Duplex/A4 AutoDuplex 210x297mm: "<</PageSize[595 
833]/ImagingBBox null/cupsPageSizeName(A4Duplex)>>setpagedevice"
*PageSize Legal/Legal 8.5x14in: "<</PageSize[612 1008]/ImagingBBox 
null/cupsPageSizeName(Legal)>>setpagedevice"
*PageSize Photo/Photo 4x6in: "<</PageSize[288 432]/ImagingBBox 
null/cupsPageSizeName(Photo)>>setpagedevice"
*PageSize PhotoFullbleed/Photo 4x6in borderless: "<</PageSize[288 
432]/ImagingBBox null/cupsPageSizeName(PhotoFullbleed)>>setpagedevice"
*PageSize Photo5x7/Photo 5x7in: "<</PageSize[360 504]/ImagingBBox 
null/cupsPageSizeName(Photo5x7)>>setpagedevice"
...
*CloseUI: *PageSize

...

*DefaultImageableArea: LetterDuplex
*ImageableArea Letter/Letter 8.5x11in: "18.00 36.00 594.00 783.00"
*ImageableArea LetterDuplex/Letter AutoDuplex 8.5x11in: "18.00 27.00 
594.00 747.00"

*ImageableArea A4Duplex/A4 AutoDuplex 210x297mm: "10.00 27.00 585.00 797.00"

This should work.
