I'll do that, but under the standard kernel it allocates video RAM just fine. It doesn't under the xen0 kernel.
It's not really fair to compare Linux running under Xen with Linux running on bare-metal. Linux on baremetal has complete, unhindered access to physical memory, and can hand out access to physical memory mappings to user processes as well (eg. X). Under Xen the situation is somewhat different in that the hypervisor controls physical memory and hands it out to all domains. The "privileged" dom0 has direct access to device registers but not necessarily to all physical memory.
UPDATE: Just tried it. I did screw up and just say "256" rather than "256MB". /dev/agpgart still doesn't exist. The only change I see is a warning in the log: (WW) intel(0): VideoRam configuration found, which is no longer recommended. (II) intel(0): Continuing with default 262144kB VideoRam instead of 256 kB. The 262144kB bit is the same as under the regular kernel but /dev/agpart still doesn't exist. This is more and more a Xen kernel issue.
On my Xen desktop which is running X just fine there is no /dev/agpart.
If that doesn't help then it's probably a general Xen problem, so asking about this upstream on xen-users[1] or xen-devel[2] lists could help.Yeah, I'm thinking about that.In any case, if you find a way to fix it please let us know.I'll keep you posted. Side note to Rich...it'd be nice if the list was in your To: as opposed to being in the Cc:. That's why I posted directly to you last time... I tend to use "Reply" not "Reply All".
