Lack of UDI support may be an encouragement or a discouragement, depending on the complexity of the device driver. On a related subject, I think Linux could use a much more coherent -- and documented -- device driver interface. Writing portable Linux device drivers requires very in-depth knowledge of the Linux 'arch' code; I find myself checking the Alpha or Sparc arch code a lot to make sure that the I/O routines and such that I call work as expected.
