No, the burst-mode ec patch is planed to be merged into 2.6.12.
So, I think it will NOT appear in that patch.
Please try to pull from http://linux-acpi.bkbits.net:8080/to-akpm
or apply patch filed at http://bugme.osdl.org/show_bug.cgi?id=3851

PS. I'm trying to maintain acpi ec driver.

Thanks
Luming
