- * There is a right way and a wrong way of doing this. Unfortunately, we
- * are forced to do it the wrong way. The right way is to be told the range
- * or ranges of I/O ports the driver(s) need access to, in order to use the
- * CONS_IOPERM ioctl() to grant access only to those ports we care about.
- * This way we can guarantee some small level of stability because a driver
- * does not have access to all ports (which would mean it could play with
- * the PIT and thus affect scheduling times, or a whole slew of other
- * nasty things). However, because XFree86 currently only enables or disables
- * ALL port access, we need to run at IOPL 3, which basically means the
- * X Server runs at the same level as the kernel. You can image why this is
- * unsafe. Oh, and this is not a problem unique to OSR5, other OSes are
- * affected by this as well.
- *
- * So, for the time being, we change our IOPL until such time as the XFree86
- * architecture is changed to allow for tighter control of I/O ports. If and
- * when it is, then the CONS_ADDIOP/DELIOP ioctl() should be used to enable 
- * or disable access to the desired ports.
