I just received an email notification from EMS (http://ems-wuensche.com/) that support for their CAN controllers is now in mainline Linux kernels. The EMS PCI products are supported in 2.6.31, and the CPC-USB product will be supported in 2.6.32. I’ve used various Linux CAN stacks in the past, but none were as well integrated as the [...]

The Socketcan test applications and utilities are now available in OpenEmbedded. The socketcan kernel modules already exist in OE. To build and deploy:
get the latest version of OE metadata
bitbake socketcan-utils-test
scp <oedir>/build/angstrom-2008.1/tmp/deploy/glibc/ipk/<machine>/socketcan-utils-test_0.0+svnr917-r0_armv5te.ipk root@<target IP address>:
And then on the target system:
opkg install socketcan-utils-test_0.0+svnr917-r0_armv5te.ipk
opkg files socketcan-utils-test
/usr/bin/tst_bcm_rx_sendto

I just added a recipe to OpenEmbedded to build the Socketcan kernel modules from the socketcan SVN. So if you are using the latest OpenEmbedded metadata, you can:
bitbake socketcan-modules
scp <oedir>/build/angstrom-2008.1/tmp/deploy/glibc/ipk/<machine>/socketcan-modules_0.0+svnr917-r0_cm-x270.ipk root@<target IP address>:
and then on the target system:
opkg install socketcan-modules_0.0+svnr917-r0_cm-x270.ipk
opkg files socketcan-modules
Package socketcan-modules (0.0+svnr917-r0) is installed on root and has the following files:
/lib/modules/2.6.27/extra/net/can/can-bcm.ko
/lib/modules/2.6.27/extra/drivers/net/can/sja1000/ems_pci.ko
/lib/modules/2.6.27/extra/net/can/can-raw.ko
