 > Aoi Shinkai, are you there? Does CF work for you with rc2 on R2D-1?
CF works fine with vanilla 2.6.24-rc2 on R2D-1.
(R2D-1 can boot from CF's rootfs with vanilla 2.6.24-rc2.)

I suspect that your R2D-1 is fpga rev1.0.
rev1.0 and rev1.1 IRL table is following.
(That is taken from old include/asm-sh/rts7751r2d.h.)

------
#if defined(CONFIG_RTS7751R2D_REV11)
#define IRQ_PCIETH     0               /* PCI Ethernet IRQ */
#define IRQ_CFCARD     1               /* CF Card IRQ */
#define IRQ_CFINST     2               /* CF Card Insert IRQ */
#define IRQ_PCMCIA     3               /* PCMCIA IRQ */
#define IRQ_VOYAGER    4               /* VOYAGER IRQ */
#define IRQ_ONETH      5               /* On board Ethernet IRQ */
#else
#define IRQ_KEYIN      0               /* Key Input IRQ */
#define IRQ_PCIETH     1               /* PCI Ethernet IRQ */
#define IRQ_CFCARD     2               /* CF Card IRQ */
#define IRQ_CFINST     3               /* CF Card Insert IRQ */
#define IRQ_PCMCIA     4               /* PCMCIA IRQ */
#define IRQ_VOYAGER    5               /* VOYAGER IRQ */
#endif
#define IRQ_RTCALM     6               /* RTC Alarm IRQ */
#define IRQ_RTCTIME    7               /* RTC Timer IRQ */
#define IRQ_SDCARD     8               /* SD Card IRQ */
#define IRQ_PCISLOT1   9               /* PCI Slot #1 IRQ */
#define IRQ_PCISLOT2   10              /* PCI Slot #2 IRQ */
#define IRQ_EXTENTION   11              /* EXTn IRQ */

And I guess that recent implementation is only for rev1.1.

arch/sh/boards/renesas/rts7751r2d/irq.c:L65
-------
/* IRLn to IRQ table for R2D-1 */
static unsigned char irl2irq_r2d_1[R2D_NR_IRL] __initdata = {
         IRQ_PCI_INTD, IRQ_CF_IDE, IRQ_CF_CD, IRQ_PCI_INTC,
         IRQ_VOYAGER, IRQ_AX88796, IRQ_RTC_A, IRQ_RTC_T,
         IRQ_SDCARD, IRQ_PCI_INTA, IRQ_PCI_INTB, IRQ_EXT,
         IRQ_TP,
};

I think that it's worth changing IRL table for rev1.0....
