Sorry, but currently, no!
PDFRead is tailored towards devices that are taller than wider i.e 480x640. While it has no problem producing 256 color .prc ebooks, it will (internally) first ensure the cropped page is less than the max. width i.e. 640 in your case, then try to shrink it vertically to be within the max. height. i.e 480. and maintain the device's aspect ratio. So the output will always be on one page for your 640x480 screen since your aspect ratio is 1.33.
What you require is for PDFRead to split the pdf page in half vertically, then render each half in turn. However, PDFRead is biased towards 'portrait type' ebook readers and as such there is no easy way to convert for 'landscape type' ebook readers.
This may require a tweaking of the algorithim used and may be incorporated into the next release if this can easily be accomplished.
In the meantime, use the landscape 'prc-mobi' profile and 'landscape' layout mode.
