I just got a Dell E6230 with the same E7 report: 73 03 0a
As noted above using the qemu serio logging doesn't work.
The driver only enables multitouch if it sees the right
name for the device in the DSDT.

The following patch (against the seabios in qemu-0.14.1)
enables the windows 7 driver (7.1211.101.114 from

) to bind successfully and alows one to get data from the serio
logging patch

Are there any standard tools for reverse engineering the
protocol - I saw mention of an alps-reg-dump but was
unable to find it?

alps-reg-dump can be found here[1]. Depending upon how different the
protocol is it may or may not be useful, however.

Just a warning that I haven't updated that in quite some time, and I'm
not even sure exactly how far I was in reverse engineering the protocol
when I stopped updating it. So it may or may not be useful to you.
