Could you help us on understanding if our system architecture is Linuxbios compliant?
I'm afraid it is not.
Step 1: A very brief description of your system: CPU and mainboard and optionally other important details. PC based portable device with Intel Celeron 800MHz 0 cache CPU, Intel 915GM north bridge and Intel ICH6-M south bridge
The problem is the northbridge. There is work in progress for 810/855 but the 915 is unchartered territory. In general recent Intel northbridges aren't supported. There has not been documentation available. If you have documentation and would be willing to help add support that would be most welcome.
Step 3: SuperIO chip on the mainboard (report the model numbers on the actual chip - doesn't appear in the lspci output) Winbond multi I/O W83627HG
While not explicitly supported, there is support for 83627EHG and 83627HF, and superio chips seem to have both rather stable programming interfaces, and readily available documentation.
Step 4: Type of BIOS device (See the question "How do I identify the BIOS chip on my mainboard?" below.) SST49LF008A
This is supported.

Intel 910/915 datasheet is available from intel's website: http://www.intel.com/design/chipsets/915g/documentation915g.htm No BIOS programmer's guide, but I don't know if Intel even makes such a thing.
The i810 mostly works, but it won't do you much good, the two chips are like apples and oranges, and I think the 855 is also sdram-only, so it'd be the same deal. A better place to start would probably be the intel e7520 or e7525, which are both somewhat similar server chips, but not the same. I looked into this about a month ago, but I decided to get a different board instead, since it lacks core 2 duo support. The southbridge may just work with the generic i82801xx with the correct driver structs added, but I haven't gotten into the datasheets for anything beyond ich5. SMBus routines should work at the very least.
