Subject: Subject: [PATCH] Intel FB pixel clock calculation fix
From: Krzysztof Halasa <khc@xxxxxxxxx>
Intel framebuffer mis-calculated pixel clocks.
The pixel clock (and thus both H and V sync) will be slower than requested, so
if you set the minimum allowed the display may not sync. In case of really
old CRT display it could theoretically damage it.
I'm using it with PAL TV (using RGB input - SCART connector) and the bug
prevented it from working at all (TV requirements are more strict and made the
bug visible).
