It is recommended to have Voipac PXA270 module with 256MB SDRAM or to enable swap partition during installation.
First compile your own kernel image based on Voipac patch file for PXA270 module and provided config file at

http://voipac.com/downloads/pxa/270/dimm/src/linux/config-linux-2.6.27-vpac1-hasty.txt

Follow guide at following location and use 2.6.27 kernel patch or later to build zImage27-256 kernel image.

Download initial ramdisk for Hasty ARMv5EL distribution and put it to TFTP root directory.

bash$> wget http://repository.handhelds.org/hasty-armv5el/installer-arm/images/versatilepb/ramdisk.gz
bash$> mv ramdisk.gz /tftpboot


Assuming having 256MB module, in u-boot bootloader execute following commands:

u-boot> tftp a1000000 zImage27-256
u-boot> tftp a2000000 ramdisk.gz
u-boot> set bootargs initrd=0xa2000000,0x2a647e console=ttyS0,38400
u-boot> wtags 80000100
u-boot> go a1000000


During installation answer some questions:

Ubuntu archive mirror hostname:         repository.handhelds.org
Ubuntu archive mirror directory:        /hasty-armv5el

Continue the install without loading kernel modules?    <Yes>


After instalation is completed modify u-boot environment bootargs variable.
(assuming installation was done to /dev/hda IDE disk drive)

u-boot> tftp zImage27-256
u-boot> set bootargs root=/dev/hda1 ro ide_core.nodma=0.0 console=ttyS0,38400
u-boot> wtags 80000100
u-boot> go


Install X.org desktop and modify default xorg.conf file

bash$> sudo aptitude install xserver-xorg-video-fbdev xorg gdm xfce4

/etc/X11/xorg.conf

Section "Device"
        Identifier      "Configured Video Device" 
        Option          "UseFBDev"              "true"
        Driver          "fbdev"
EndSection
