+ *	Copyright (C) 2000 Philipp Rumpf <prumpf@tux.org>
+ *   - based on skeletonfb, which was

+ * - HP Xhp cfb-based X11 window driver for XFree86
+ *	(c)Copyright 1992 Hewlett-Packard Co.
+ *
+ * 
+ *  The following graphics display devices (NGLE family) are supported by this driver:
+ *
+ *  HPA4070A	known as "HCRX", a 1280x1024 color device with 8 planes
+ *  HPA4071A	known as "HCRX24", a 1280x1024 color device with 24 planes,
+ *		optionally available with a hardware accelerator as HPA4071A_Z
+ *  HPA1659A	known as "CRX", a 1280x1024 color device with 8 planes
+ *  HPA1439A	known as "CRX24", a 1280x1024 color device with 24 planes,
+ *		optionally available with a hardware accelerator.
+ *  HPA1924A	known as "GRX", a 1280x1024 grayscale device with 8 planes
+ *  HPA2269A	known as "Dual CRX", a 1280x1024 color device with 8 planes,
+ *		implements support for two displays on a single graphics card.
+ *  HP710C	internal graphics support optionally available on the HP9000s710 SPU,
+ *		supports 1280x1024 color displays with 8 planes.
+ *  HP710G	same as HP710C, 1280x1024 grayscale only
+ *  HP710L	same as HP710C, 1024x768 color only
+ *  HP712	internal graphics support on HP9000s712 SPU, supports 640x480, 
+ *		1024x768 or 1280x1024 color displays on 8 planes (Artist)
