I have some raster data (ASCII grid files) that use a custom rotated-pole projection, that I'd like to reproject into something more useful, such as lon/lat WGS84. A description of the grid projection is here, but I can't see how I can use this to create a projection string for use in GIS.

This SE question seems to discuss using rotated pole data, but I can't work out how to apply it to my problem: Lon/lat transformation
I found a thread here asking exactly same question (about the same dataset), but with no replies: http://lists.osgeo.org/pipermail/gdal-dev/2011-March/028174.html
The header of the ASCII grid data looks like this:
ncols 39
nrows 52
xllcorner -0.50
yllcorner -0.50
cellsize 1.00
