Hi,
	I have a similar card and a similar problem. My card is a

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV635/M86 [Mobility Radeon HD 3650] (prog-if 00 [VGA controller])
        Subsystem: Hewlett-Packard Company Device 30e7
        Flags: bus master, fast devsel, latency 0, IRQ 35
        Memory at c0000000 (32-bit, prefetchable) [size=256M]
        I/O ports at 7000 [size=256]
        Memory at d8300000 (32-bit, non-prefetchable) [size=64K]
        Expansion ROM at d8320000 [disabled] [size=128K]
        Capabilities: [50] Power Management version 3
        Capabilities: [58] Express Legacy Endpoint, MSI 00
        Capabilities: [a0] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?>
        Kernel driver in use: radeon
        Kernel modules: radeon

I get the same symptoms that you describe but that as far as I remember only happens when I leave the computer unattended for some time.

Today while leaving for lunch I changed to display to a VT and I got this error:

[19702.821095] radeon 0000:01:00.0: failed to get a new IB (-35)
