But you see that makes no sense at all. The source was downloaded for debian
etch. Barring the commented line, the source is equivalent to the binary
version that it replaced. Which ran on the same custom kernel that I have
(2.6.15.1).

Could it be that had that bug not been present in the stock Debian testing
packages, this error would have appeared earlier ? Or do I need to apply a
patch to my current kernel to make it work somehow. I am quite confused
about this.
