It supports ia64 and does about what you are doing on the dump side, and has dump analysis tools. If you've already considered this just delete this.

I've already wrote a dump modules driver for linux-parisc. This module goal is to create a memory image on a swap area, and at reboot time to save it to disk with all kernel modules, in order to analyze it after by "support" people with tools like gdb/p4. The problem while dumping is that the dump modules cannot trust anymore the system, so dumping means: no interruption, no disk driver, no buffer, nothing. The solution is to use low level call. For parisc I use the IODC calls, for ia64 I think I'll use the EFI calls. My questions: -do you think it is a "good" and realistic solution. -because I think "yes", does exist somewhere an example of reading/writing with EFI call on disk using BLOCK IO. I've already looked in elilo, but it seems that it use FS access.
