Things were a bit better with the That's just normal. We do not save the content of the consoles... With a framebuffer driver, just switching VTs once restores the previous content, unfortunately that does not work with VGA mode since the vga display buffer is on the video card memory which is cleared or garbled by VBE POSTing the device. > framebuffer, but garbage was still there.

I am running > Debian. I am using the framebuffer, and the graphic card is a SiS M760. I think it is pretty similar to the A7640 i have here, apart that that one has an Athlon64. It also has a strange "-f -a1 -p -s" entry in the whitelist, i'll have to investigate this one too. > # lspci > 00:00.0 Host bridge: Silicon Integrated Systems [SiS] 760/M760 Host (rev 03) > 00:01.0 PCI bridge: Silicon Integrated Systems [SiS] SG86C202 > 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS963 [MuTIOL > Media IO] (rev 25) > 00:02.1 SMBus: Silicon Integrated Systems [SiS] SiS961/2 SMBus Controller > 00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] > 00:02.6 Modem: Silicon Integrated Systems [SiS] AC'97 Modem Controller > (rev a0) > 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] > AC'97 Sound Controller (rev a0) > 00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 > Controller (rev 0f) > 00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 > Controller (rev 0f) > 00:03.3 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller > 00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI > Fast Ethernet (rev 91) > 00:06.0 FireWire (IEEE 1394): Texas Instruments TSB43AB22/A > IEEE-1394a-2000 Controller (PHY/Link) > 00:09.0 CardBus bridge: O2 Micro, Inc.

Well, if "s2ram -f -s" is actually enough to get the light back on and just switching consoles after resume gets you the beautiful framebuffer content back, then i'd be glad to commit that one to the whitelist. If it does not help, i'd prefer to first try is on the A7640 i have here and then decide what to do. Since i am going on vacation for two weeks, this won't happen real soon, unfortunately.
