If using 2.3.x kernels you need to enable CONFIG_OSF_PARTITION to access
SRM-compatible disks prepared on Alpha. The kernel will be able to mount
these partitions then.
For 2.2.x kernels the option is exactly the same but it is not
user-settable -- it's set unconditionally in linux/genhd.h when compiling
for Alpha. I suppose you may just change the "#ifdef __alpha__" that
precedes it to "#if 1" to set it unconditionally for every architecture.

If the disk was used for Linux it almost surely has the ext2 filesystem.
If it was used for OSF/1 then it has the ufs filesystem (or an advfs
filesystem Linux cannot handle).

Looking at bselect() from the current fdisk it will not handle OSF/1
disklabels unless on Alpha so you cannot look at these on an i386/Linux
machine. You may try to compile minlabel -- not sure if it will work for
i386/Linux straight out of the box, though.
