As of v2.1.0, falcon_decode_var() contains a quirk to fix a rounding error, as explained by Günther Kelleter on Fri, 30 Aug 1996: This diff removes the now obsolete Falcon video option "pwrsave", and fixes a rounding error that is triggered by the resolution switching X server (those who use the pixel clock value 39722 in their /etc/fb.modes should change it to 39721). However, this causes the modified video mode returned by falcon_decode_var() to not match the video mode returned by falcon_encode_var(). Fix this by dropping the quirk. Unfortunately /etc/fb.modes in fbset was never updated, so the "640x480-60" mode still contains the wrong pixclock. Hence this change may introduce a regression.
