33 * Driver for the Sun ZX display adapter. This would be called 'leo', but
34 * NetBSD/amiga already has a driver by that name. The XFree86 and Linux
35 * drivers were used as "living documentation" when writing this; thanks
36 * to the authors.
37 *
38 * Issues (which can be solved with wscons, happily enough):
39 *
40 * o There is lots of unnecessary mucking about rasops in here, primarily
41 * to appease the sparc fb code.
42 *
43 * o RASTERCONSOLE is required. X needs the board set up correctly, and
44 * that's difficult to reconcile with using the PROM for output.
