40 * Driver for the Sun ZX display adapter. This would be called 'leo', but
41 * NetBSD/amiga already has a driver by that name. The XFree86 and Linux
42 * drivers were used as "living documentation" when writing this; thanks
43 * to the authors.
44 *
45 * Issues (which can be solved with wscons, happily enough):
46 *
47 * o There is lots of unnecessary mucking about rasops in here, primarily
48 * to appease the sparc fb code.
49 *
50 * o RASTERCONSOLE is required. X needs the board set up correctly, and
51 * that's difficult to reconcile with using the PROM for output.
