The most current version (1.34) of ndiswrapper works with the 2.6.19 kernel series.
It seems that the new kernel, 2.6.19, has a specific check that taints the kernel when the ndiswrapper module is loaded. This restricts the symbols which ndiswrapper can access, which seems to be causing my system to freeze. I'm going to try patching my kernel (by removing the kernel check which adds a “taint” flag to the ndiswrapper module) and see if that helps things out… 1)
