for debugging purposes I set the baudrate to 74880 in the sketch and serial monitor (manually in the preferences.txt: serial.debug_rate=74880 as this setting is not av. in ide <1.6.7) so I can see the bootloader messages in the serial monitor as well as my debug messages. This isn't in any way related to the baud settings in your screenshot.
Maybe you won't see the bootloader or your debug message when pluging the unit into your PC because this is happening to quick (before the OS recognizes the new device). But doing a reset on the esp while pluged in should bring the messages
I do have the exact problem. When board is reset(by connecting rst of ESP to gnd) or by replugging the USB - program no longer exists on chip. I also use Arduino.
My connections are:
GPIO0 pull-up (has circuit which puts is automatically LOW when DTR pin from CP2102 is enabled, check it here: http://i67.tinypic.com/2lv003l.png )
GPIO2 pull-up
CH_PD pull-up
RESET pull-up
GPIO15 pull-down
When reconnected, I get this message at 74880 baud rate.

I'm totally confused, what am I doing wrong?
In such case, you need first to erase the whole Flash, and then re-upload the firmware :
esptool.py --port /dev/ttyUSB0 erase_flash
esptool.py can be found at https://github.com/themadinventor/esptool
