	 * The following chips should be detected by this function. Known

	 * register values are listed. Registers 0x3d .. 0x3e are undocumented

	 * for most of the chips, yet appear to return a well defined value.

	 * Register 0xff is undocumented for some of the chips. Register 0x3f

	 * is undocumented for all chips, but also returns a well defined value.

	 * Values are as reported from real chips unless mentioned otherwise.

	 * The code below checks values for registers 0x3d, 0x3e, and 0xff,

	 * but not for register 0x3f.
