Hi, re the ata driver and CS5530, Soren Schmidt asked:

Ok (it's _not_ 0):
-----
geode# pciconf -r pci0:18:2 0x20
0000fc01
geode# pciconf -r pci0:18:2 32
0000fc01

Is this 0x20 on F2, F2BAR4? Is it supposed to be
0, not the "I/O mapped Bus Master IDE Registers..."?
I have a 5530 manual (although I'm uncertain if
all the "5530s" really look the same in all
ways...). Bits 31:4 are the bus master IDE base
address (0xfc0). The RO 1 indicates a 16-byte I/O range.
I am using a reasonably recent National Semiconductor
Centaurus 2 development board. My understanding
is that this is National's current reference
development platform. It uses National's XpressROM
BIOS, intended for use with the GX1 and CS5530.
This BIOS seems to evolve rather rapidly, it
doesn't look like the BIOS is very recent. The
BIOS screen says:
------
Rev: v2.22 B Built: 07/01/2002 07:54:38

Floppy A:1.44M Drive 80:41174MB COM1:03F8 LPT1:0378 XpressROM V3.2.5

CPU Voltage 2.20 9211: B1/C1

I'll try to track down "r_bmio" life.
The same hardware runs the "/boot/kernel.last_good/kernel"
"FreeBSD 5.0-CURRENT #3: Mon Jan 20 ... 2003"
fine, there are no obvious driver problems. Other
than the expected -current deltas, the only other
difference between the two systems that I know of
is that the older system is not using the TSC
clock. I'll see if that changes things. They
are basically both GENERIC.
Other misc info:
