thorpej 3db7555465 Returning ENODEV is not correct in a poll entry point. Instead, since 
read/write returns an error, use seltrue().

abrown 19b3f7f50b Initial commit of cg14 framebuffer driver for Sun4m SPARCs. 
- This driver supports the on-board mbus-based cgfourteen (sometimes referred
  to as "SX") video hardware present on SS20-class machines.
- It does *not* support any of the SX acceleration features.
- It does support the 8-bit mode of the hardware, and looks to X like
  a cgthree.
- It does support the cg6-style hardware cursor, even when running X in
  cgthree emulation.
- It does support DPMS power-down of compatible displays on later-revision
  cg14's.
- There is code to support the true color (32-bit) mode of the cg14 as
  cg8 emulation, but it is disabled by default because it is most likely
  broken. #define CG14_CG8 to turn it on.

The driver is not yet installed in the conf files, but I will do so
shortly...
