Is there really no space between the "eth0=tuntap,,, 192.168.1.101" and
"noprocmm"?  If so, that would cetainly break something.

No there isn't. I don't know why copy & paste cause this effect on the mail message.
I also added mem=512M parameter, but I'm getting the same result.
Maybe there's some problem with new kernels only.
