I have exactly the same problem with Intrepid Alpla6, which is using the 2.4.1-1ubuntu6 version of the intel driver.
My motherbord is a Gigabyte EG43M-S2H with the G43 IGP. ~$ lspci 00:00.0 Host bridge: Intel Corporation 4 Series Chipset DRAM Controller (rev 03) 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) 00:1a.0 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #4 00:1a.1 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #5 00:1a.2 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #6 00:1a.7 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #2 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller 00:1c.0 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Port 1 00:1c.5 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Port 6 00:1d.0 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #1 00:1d.1 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #2 00:1d.2 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #3 00:1d.7 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #1 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 90) 00:1f.0 ISA bridge: Intel Corporation 82801JIB (ICH10) LPC Interface Controller 00:1f.2 IDE interface: Intel Corporation 82801JI (ICH10 Family) 4 port SATA IDE Controller 00:1f.3 SMBus: Intel Corporation 82801JI (ICH10 Family) SMBus Controller 00:1f.5 IDE interface: Intel Corporation 82801JI (ICH10 Family) 2 port SATA IDE Controller 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Device 8213 Ubuntu can not start with the default session. It works with xfce4 though. But when the program is doing some more intensive graphics, like animation, window expanding e.g., the X server will often crash. Some other users are also experiencing this with the G43 chipset.
