[Openchrome-users] 答复: [Openchrome-devel] Getting ready to release OpenChrome Version 0.3.4

[黄然]

Hi Kevin,

	Now that KMS is the trend and being adopted by main graphics cards vendor(Intel, AMD/AIT), so I think KMS driver is needed to be tested as you said here.
	I will get a VX900 chipset based board and try/test OpenChrome KMS driver then based on my experience for 5 years' working on AMD open source RADEON KMS driver.
	Simultaneously, I prefer to get/buy more old VIA boards as you have done.
	Keep contact.

Sincerely，
Frank
