Faults in drivers [...] would be less likely to destabilize the entire system. [...] A process can communicate with hardware by mapping the relevant I/O memory directly into its address space, for example; that is how the X server works with video adaptors.
Would the user space driver make the system really that more stable? I mean the X server can easily lock up my system even from user mode...
