ok, sorry for the dual post, but they are somewhat related.
1. I havent really put much thought to using linuxbios on a laptop, but a recent post has planted a bug in my brain to try and get it to work on some of the older laptops i have laying around. How many people have tried to get linux bios on their laptops, and how well does it work.
this issue now prompts this quesion:
2. What type of "bios savior" options are there for laptops? or is that just a pipe dream at this point?

we tried with IBM but IBM wouldn't let IBM put linuxbios on an IBM laptop.
Yes, this is all true.

linuxbios fallback would work fine as a bios savior. Plus, many laptops have on options if you fry the flash.

Just came across this today: Lindows Notebook http://info.lindows.com/mobilepc/mobilepc.htm
This may be a good candidate as well.

The trick with laptops is getting LinuxBIOS to work along with the system/power management controller. I'd suggest working with the SiS based laptops or the new Intel Centrino http://developer.intel.com/design/chipsets/mobile/index.htm?iid=devnav_btn1+... laptops and tablets that are now or very soon to pop up everywhere.
Several vendors are using the Hitachi H8s http://www.hitachisemiconductor.com/sic/jsp/japan/eng/products/mpumcu/816bit... for a system/power management controller. Which has a rich development environment http://www.hitachisemiconductor.com/sic/jsp/japan/eng/products/mpumcu/tool/d... unfortunately only for windowz and Solaris. Depending on the vendor the security feature may not be enabled on the H8s F-ZTAT (flash) so firmware may be modified, otherwise you'll have to get LinuxBIOS to work around it.
Another issue is that video BIOS is combined with the system BIOS since many laptops use chipsets with integrated graphics. Getting your hands on the video BIOS binary may be a problem. Don't even ask for video BIOS source since the binary is typically released along with a modification tool that does not require the BIOS source for modification.
Most 830 based designs also use the H8s but will probably soon disappear from store shelves.

I plan to use a PLCC extractor on mine. Not an option for everyone though.
