Comment 109 for bug 362582

Well, I do have a documentation from National Semiconductors, but there is nothing that would define frequencies or bandwidths - only the sync pulses can be set, and intput to syncs. So I played writing values into all other registers with i2cset, but with little success - not any change, actually, except for the mentioned register. Ok, and you could block off the screen as well by disabling the sync pulses (not much of a surprise, I guess).

However, leaving all that aside - I'm no longer able to talk to the chip, upon rebooting i2cdetect gave me all blanks on bus #6. I really wonder what is going on. Could it be that there is some additional "gating" going on that blocks off access to this chip unless another register is set? Is that typical?
