CELF had big involvement in OLS 2006. CELF was a sponsor of OLS and we had a number of meetings at and around the event. There were presentations and BOFs by many CELF members. Also, we continued our tradition of handing out prizes at the closing keynote address.
Here are some of notes and presentations from the event.
In this BOF, Tim gave his "State of Embedded Linux" talk. He described some what's happened with Linux in the last year, related to its use in embedded devices. This includes an overview of things recently mainlined (like Linux-tiny patches), as well as ongoing work and research in areas like power management for embedded devices, system memory size, bootup time improvements, realtime, measurement tools, etc.
Here is Tim's presentation: Media:OLS2006-Embedded-BOF-2.ppt
Here are PORTIONS of Tim's presentation, with links to relevant articles (mostly on lwn.net) /\ - please see the file for the full presentation.

size issue
corporate developer participation in community
At this meeting we discussed some of CELF's initiatives and member company projects.
The following presentation introduced the topics, and had information about the CELF Test Lab: Media:CELF-Projects-BOF.ppt
See more about the lab in the BOF slides (see above).
Ikeda described his examination to make clear the size impact (image size and memory effect) of different kernel config options.

Discussion led by Tim.
We discussed CELF's proposal for creating a list of technology projects to focus on for the year
What projects deserve focused CELF attention??
Does anyone need hardware that CELF or it's members can provide?
Should we do a "hackfest"?

/\ Please note that several other sessions at OLS reflect work that is sponsored or funded (in whole or in part) by CELF member companies.
CELF produced a guide to OLS sessions for embedded developers]. This might help you look through the OLS 2006 proceedings for presentations of interest. The Proceedings are available at: http://www.linuxsymposium.org/2006/proceedings.php
CELF members showed a number of demos of their current open source projects. Come see live demonstrations of technology developed for using and customizing Linux in Consumer Electronics products.
CELF had several prizes to hand out again, as a way of saying "Thank You" to the open source community.
The prizes were handed out by Tim Bird at the final keynote:
