Siemens SX 541, SMC SMC7908VoWBRB
both nearly identical hardware, smc has a bigger switch.
have tryed to run openwrt with a from stefan (se154) and it looks like we can bring this up...
2 bootlogs attached, may anybody can help...
would like to get this hardware added to openwrt...

this bootlog, we get when a warm boot from console was done after flashing.

Done!
