regardless of the license-nazi issues of his kernel modules, all those things on IRQ 11 looks questionable. i run the nvidia binary driver but it gets its own IRQ, same as the ATI fglrx...these are both on amd64 motherboards... on my ~2001 ASUS athlon32 mobo, with win32, everything _would_ end up on a single IRQ, unless disabling ACPI, in which case they would be nicely distributed. no idea what this all means, but someone else agrees:
