I also have this problem. I could get around it by running a previous kernel from the grub list, but since updating today to the latest kernel I can't do this any more because it refuses to boot up the previous kernel (now 6 down the list).
It's very depressing that this is taking so long to fix. ATI on AMD64, but running 32 bit system. lspci gives: 00:00.0 Host bridge: ATI Technologies Inc RS480 Host Bridge (rev 10) 00:02.0 PCI bridge: ATI Technologies Inc RS480 PCI-X Root Port 00:12.0 IDE interface: ATI Technologies Inc IXP SB400 Serial ATA Controller 00:13.0 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller 00:13.1 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller 00:13.2 USB Controller: ATI Technologies Inc IXP SB400 USB2 Host Controller 00:14.0 SMBus: ATI Technologies Inc IXP SB400 SMBus Controller (rev 12) 00:14.1 IDE interface: ATI Technologies Inc IXP SB400 IDE Controller 00:14.3 ISA bridge: ATI Technologies Inc IXP SB400 PCI-ISA Bridge 00:14.4 PCI bridge: ATI Technologies Inc IXP SB400 PCI-PCI Bridge 00:14.5 Multimedia audio controller: ATI Technologies Inc IXP SB400 AC'97 Audio Controller (rev 02) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:00.0 VGA compatible controller: ATI Technologies Inc RV515 [Radeon X1300] 01:00.1 Display controller: ATI Technologies Inc RV515 [Radeon X1300] (Secondary) 02:03.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
