Problem with Space Internal

Hi,
I have a HTC Desire with Cyanogenmod 7.1 and my problem is the internale Space. I would partition with ROM Manager(5.006) but when I partition SD(256 Mb Ext4 and 0 Swap) reboot the system and I have a error
The log is:
"can't open /dev/tty0: No such file or directory
framebuffer: fd 3 (480 x 800)
ClockworkMod Recovery v2.5.0.7
I:Set boot command "boot-recovery"
Command: "/sbin/recovery"

Can you help me??
