not really, it just means that in the kernel - are mapped to _; modprobe tools 
handle both cases, just modinfo reports the filename which can include '-', but 
it can still handle both.

lspci and most tools just report it as it's really named (depending on 
filename). modules.dep and modules.descr, etc... has the name as it is as well, 
meaning there can be '-' in the name.

i just see this workaround being effective to handle lstdetect, which somehow 
forces all of it being lowercase...

i don't know how much of lstdetect is hardcoded and how much of it is 
generated, but imho the cleanest way would be to fix lstdetect, so that it 
gives the proper module names...

i've been looking at a way to fix the module list window for choosing, but the 
problem isn't as simple as i thought, since insmod looks at filenames... which 
is another workaround.

@thierry: i donno what you think of it, but imo:
A) fixing lstdetect would be the cleanest way (maybe not the simplest)
B) perhaps in the comparing i can workaround this, but the compare code will 
not be as simple as it should...
