you wrote in the a previous thread that one can use gdal 1.5 directly to
access a WMS ressource which is defined in an xml file (see snippet below).
As 1.5 is out (and I compiled with MrSid support - works nicely by the
way), I looked but could find no information on that feature. Could you
please elaborate how I can use this instead of setting up a mapserver on
localhost?
my understanding was - feel free to correct me - dylan was refering to
the OGR/GDAL vrt driver.

I would rather guess it was the "WMS -- Web Map Services" driver:
http://www.gdal.org/frmt_wms.html
The page explains that you have to create an xml file such as this:
<GDAL_WMS>
<Service name="WMS">
<Version>1.1.1</Version>
<ServerUrl>http://onearth.jpl.nasa.gov/wms.cgi?</ServerUrl>
<SRS>EPSG:4326</SRS>
<ImageFormat>image/jpeg</ImageFormat>
<Layers>modis,global_mosaic</Layers>
<Styles></Styles>
</Service>
<DataWindow>
<UpperLeftX>-180.0</UpperLeftX>
<UpperLeftY>90.0</UpperLeftY>
<LowerRightX>180.0</LowerRightX>
<LowerRightY>-90.0</LowerRightY>
<SizeX>2666666</SizeX>
<SizeY>1333333</SizeY>
</DataWindow>
<Projection>EPSG:4326</Projection>
<BandsCount>3</BandsCount>
</GDAL_WMS>
I guess (but have never tried) that this would lead to an r.in.gdal line
such as:
r.in.gdal in=YourFile.xml out=GRASSLayerName
