This is essentially what it is doing already. It renders "y-stripes" across the whole horizontal area. However inkscape still seems to be loading and processing the full SVG file or it wouldn't die from these memory crashes I assume. The cutting is being done by Perls GD library functions.

err, the inkscape -w and -h parameters are using $SizeX and $SizeY in function svg2png.
those 2 parameters are calculated on line 767 and passed ti svg2png:
    my $Width = 256 * (2 ** ($Zoom - $ZOrig));  # Pixel size of tiles
    my $Height = 256; # Pixel height of tile

So the image heigth and width should never be some weird number.

Those x,y numbers are calculated on lines 807-820 which contain scary projection stuff which is bound to be weird decimal numbers. DOn't ask me to explain those though :-).
