Tried with loady command in u-boot and ymodem option from minicom. With this combination I am able to transfer and run uImage.
I tested this again on OMAP3 systems (including Beagle):

As you can see, this is working without any problems.
So either your host systems is still misconfigured (which I consoder most likely), or your target system hast issues (instable RAM and.or serial port, etc.), or you have been doing something wrong.
I don't think there is a problem in the mainline U-Boot code.
