SubjectAlpha MIATA + PCI - trouble?

I'm now trying soundcard S3 SonicVibes with Alpha MIATA (pyxis),
but I have big trouble with access to DMA registers. These registers are
accessible via non-standard PCI interface (I/O address - port address -
is stored in 32-bit PCI registers 0x40 & 0x48). I don't know how access to
PCI bus work with alpha systems, but seems that some remapping must be
done before is specified i/o port accessible. Can someone help me with
this problem? Please, send CC: directly to me (I'm only digest reader).
Other problem: When kernel (currently 2.1.119) is booting kernel
show these messages:

[some dump of registers]
kernel: PYXIS machine check NOT expected
kernel: pyxis_machine_check: vector=0x660 la_ptr=0xfffffc00002085a0
kernel: ^I^I pc=0xfffffc000047be88 size=0x1b8 procoffset=0xd8 sysoffset 0x160
These messages appear when ALSA sound driver access to PCI
registers, too.
