Obtained patched ALSA 1.0.9b_26  from Realtek.com.tw.
Won't build on Fedora 2.6.15 kernel (which uses ALSA 1.0.10).
Tried porting ASUS patches to 2.6.15 kernel; no change.
Built a FC4 2.6.11 kernel then tried building stock Realtek 
package. Package builds and installs, but problem remains.

Sound files longer than the buffer length (65536) hang.
With some debugging enabled, I see in syslog:
ALSA sound/pci/via82xx.c:794: zero position is read
and
ALSA sound/core/pcm_native.c:1460: playback drain error (DMA or IRQ
trouble?)
When the module is installed, I see
ACPI: PCI Interrupt 0000:00:11.5[C] -> Link [LNKC] -> GSI 5 (level, low)
  -> IRQ5
