[driverloader] More concisely

Hi Cristiano,

If I recall correctly you are using a SuSE kernel. These usually have 
8k of stack, which is sufficient (based on the testing that we have 
done) for the USR805410 (TI ACX 111) Windows driver, so you shouldn't 
worry about this. Intel Centrino drivers (2100 and 2200bg) are much 
larger stack consumers and more problematic, especially when combined 
with Fedora kernels compiled with small 4K stacks.

In order to eliminate or at least reduce the stack overflow risks we 
are working to increase the awareness of chipset manufacturers that 
their drivers can also be used under Linux, making Fedora kernels and 
patches for larger stack sizes available, and implementing special 
workarounds in driverloader itself that attenuate the problem.
