Little FYI/Tip or you. When I build a kernel, I do something like the
following:

Leviathan boot # tree
.
|-- 2.6.23-r6
| |-- Config.Leviathan
| |-- Leviathan
| `-- System.map-Leviathan
|-- 2.6.23-r8
| |-- Config.Leviathan
| |-- Leviathan
| `-- System.map-Leviathan
|-- boot -> .
|-- grub
| |-- default
| |-- device.map
| |-- e2fs_stage1_5
| |-- fat_stage1_5
| |-- ffs_stage1_5
| |-- grub.conf
| |-- grub.conf.sample
| |-- grub.conf~
| |-- iso9660_stage1_5
| |-- jfs_stage1_5
| |-- menu.lst -> grub.conf
| |-- minix_stage1_5
| |-- reiserfs_stage1_5
| |-- splash.xpm.gz
| |-- stage1
| |-- stage2
| |-- stage2_eltorito
| |-- ufs2_stage1_5
| |-- vstafs_stage1_5
| `-- xfs_stage1_5
`-- lost+found

Leviathan boot #


As you can see, for each kernel I make, I copy the .config to the
/boot/<`uname-r`>/ dir so that I always have a copy.

But to answer your original request, you can try looking for
/proc/config.gz .... there is an option (I believe it is the default
setting) to throw a copy of /usr/src/linux/.config in there. If it is
there, you can do something like this

- -> gzcat /proc/config.gz >>/usr/src/linux/.config <--

Give that a shot and see what happens.
